Before Installation or Maintenance
- Shipping and Moving the Machine -
• Work carefully when lifting or moving the machine. If the machine is heavy, two or more customer
engineers may be required to prevent injuries (muscle strains, spinal injuries, etc.) or damage to the
machine if it is dropped or tipped over.
• Personnel moving or working around the machine should always wear proper clothing and footwear.
Never wear loose fitting clothing or accessories (neckties, loose sweaters, bracelets, etc. ) or casual
footwear (slippers, sandals, etc.) when lifting or moving the machine.
• Always unplug the power cord from the power source before you move the machine. Before you
move the machine, arrange the power cord so it will not fall under the machine.
- Power -
• Always turn the machine off and disconnect the power plug before doing any maintenance procedure.
After turning the machine off, power is still supplied to the main machine and other devices. To prevent
electrical shock, switch the machine off, wait for a few seconds, then unplug the machine from the
power source.

After removing covers or opening the machine to do checks or adjustments, avoid touching electrical
components or moving parts (gears, timing belts, etc.).
• After turning the machine on with any cover removed, keep your hands away from electrical com-
ponents and moving parts. Never touch the cover of the fusing unit, gears, timing belts, etc.
- Installation, Disassembly, and Adjustments -
• After installation, maintenance, or adjustment, always check the operation of the machine to make
sure that it is operating normally. This ensures that all shipping materials, protective materials, wires
and tags, metal brackets, etc., (attached to protect the machine during shipping), have been removed
and that no tools remain inside the machine.
• Never use your fingers to check moving parts that are causing spurious noise. Never use your fingers
to lubricate moving parts while the machine is operating.
- Special Tools -
• Use only standard tools approved for machine maintenance.

• For special adjustments, use only the special tools and lubricants described in the service manual.
Using tools incorrectly, or using tools that could damage parts, could damage the machine or cause
injuries.
During Maintenance
- General -
• Before you begin a maintenance procedure always switch the machine off.
• Disconnect the power plug from the power source.
• Allow the machine to cool for at least 10 minutes.
• Avoid touching the components inside the machine that are labeled as hot surfaces.
- Safety Devices -
• Never remove any safety device (a fuse, thermistor, etc.) unless it requires replacement. Always
replace a safety device immediately.
• Never do any procedure that defeats the function of any safety device. Modification or removal of a
safety device (fuse, thermistor, etc.) could cause a fire and personal injury. After removal and re-
placement of any safety device, always test the operation of the machine to ensure that it is operating
normally and safely.
• For replacement parts use only the correct fuses, thermistors, circuit breakers, etc. rated for use with
the machine. Using replacement devices not designed for use with the machine could cause a fire
and personal injuries.
- Organic Cleaners -
• During preventive maintenance, never use any organic cleaners (alcohol, etc.) other than those de-
scribed in the service manual. (Refer the “2. Preventive Maintenance” in the Service Manual.)
• Make sure the room is well ventilated before using any organic cleaner. Always use organic solvents
in small amounts to avoid breathing the fumes and becoming nauseous.
• Switch the machine off, unplug it, and allow it to cool before doing preventive maintenance. To avoid
fire or explosion, never use an organic cleaner near any component that generates heat.
• Wash your hands thoroughly after cleaning parts with an organic cleaner to avoid contamination of
food, drinks, etc. which could cause illness.
- Lithium Batteries -

• Always replace a lithium battery on a PCB with the same type of battery prescribed for use on that
board. Replacing a lithium battery with any type other than the one prescribed for use on the board
could lead to an explosion or damage to the PCB.
• Never discard used batteries by mixing them with other trash. Remove them from the work site and
dispose of them in accordance with local laws and regulations regarding the disposal of such items.
- Ozone Filters -
• Always replace ozone filters as soon as their service life expires (as described in the service manual).
An excessive amount of ozone can build up around machines that use ozone filters if they are not
replaced at the prescribed time. Excessive ozone could cause personnel working around the machine
to feel unwell.
- Power Plug and Power Cord -
• Before serving the machine (especially when responding to a service call), always make sure that the
power plug has been inserted completely into the power source. A partially inserted plug could lead
to heat generation (due to a power surge caused by high resistance) and cause a fire or other
problems.
• Always check the power plug and make sure that it is free of dust and lint. Clean it if necessary. A
dirty plug can generate heat which could cause a fire.
• Inspect the length of the power cord for cuts or other damage. Replace the power cord if necessary.
A frayed or otherwise damaged power cord can cause a short circuit which could lead to a fire or
personal injury from electrical shock.
• Check the length of the power cord between the machine and power supply. Make sure the power
cord is not coiled or wrapped around any object such as a table leg. Coiling the power cord can
cause excessive heat to build up and could cause a fire.
• Make sure that the area around the power source is free of obstacles so the power cord can be
removed quickly in case of an emergency.
• Make sure that the power cord is grounded (earthed) at the power source with the ground wire on
the plug.
• Connect the power cord directly into the power source. Never use an extension cord.
• When you disconnect the power plug from the power source, always pull on the plug, not the cable.
After Installation
- Disposal of Used Items -

• Ink is flammable. Never attempt to incinerate empty ink cartridges.
• Always dispose of used items in accordance with the local laws and regulations regarding the disposal
of such items.
• To protect the environment, never dispose of this product or any kind of waste from consumables at
a household waste collection point. Dispose of these items at one of our dealers or at an authorized
collection site.
- Points to Confirm with Operators -

At the end of installation or a service call, instruct the user about use of the machine. Emphasize the following
points.
• Show operators how to remove jammed paper and troubleshoot other minor problems by following
the procedures described in the operating instructions.
• Point out the parts inside the machine that they should never touch or attempt to remove.

Merging Applications on One SD Card
Location of SD Card Slots
The machine has three SD card slots:

• C1 is for applications provided on SD cards. If more than one option is to be installed, the applications
must be merged on the same SD card. (see ‘Merging Applications’).
• C3 is used for servicing only. Otherwise this slot should always be empty.
• The data necessary for authentication is transferred with the application program to the target SD
card.
• Do not use an SD card if it has been used with a computer. Correct operation is not guaranteed if this
type of SD card is used.
49

1. Installation
• The SD card is the only evidence that the customer is licensed to use the application program. The
service technician may occasionally need to check the SD card and its data to solve problems. SD
cards must be stored in a safe location at the work site.A licensing agreement prohibits copying of
the PostScript SD card. However, you can copy an application from another SD card to the PS SD
1 card. (This restriction may apply to other SD cards as well.)
• If an SD card was used to combine applications on that card, that SD card cannot be used for any
other purpose.
Merging Applications
Do this procedure to put more than one application on one SD card.
• During this procedure, make sure that you put the source SD card and the target SD card in the correct
slots.
1. Turn off the machine.

2. Remove the SD card slot cover [1] ( x2).
3. Put the Source (DOS) SD card [2] in C3. This card contains the application that you want to
copy.

14. Turn the machine off again, then:
• Attach the SD card slot cover.
• Tape the copied source card to the faceplate of the controller box.
• Attach the rear cover of the machine.
• After an SD card is copied, it cannot be used. But it must be stored at the customer site, to serve as
proof of purchase by the customer.
• The original card can also be used to perform an undo procedure (SP 5873 002). Before you tape
the copied SD card to the machine, label it carefully so that you can identify it easily if you need to
do the undo procedure at a later time (see ‘Undo Exec’).
Undo Merging
1. Turn the main switch off.

2. Put the SD card with the merged applications in C1.
3. Insert the original destination SD card (the one taped to the faceplate of the controller box)

3. After replacing the LD board, do SP 2-109 to adjust the laser beam pitch (described below).
Laser Beam Pitch Adjustment

After replacing the LD board, do the laser beam pitch adjustment. There are two procedures: one for 400
dpi, and one for 600 dpi. These use the following SPs.
SP2110 Test Mode Dpi (0: 400 dpi, 8: 600 dpi)
SP2109-01 LD Beam Pitch Adjustment – 400 dpi
SP2109-02 LD Beam Pitch Adjustment – 600 dpi
SP2109-03 LD Beam Pitch Adjustment – 400 dpi Initial Setting
SP2109-04 LD Beam Pitch Adjustment – 600 dpi Initial Setting
79

1. If you do not have an SMC Report for reference, do SP5990-002 to print the SMC Report
so you can look up and match the SP numbers below with the correct name.
2. Set SP2110 to "0" (for 400 dpi), or to "8" (for 600 dpi).
3. Execute SP2109-08 to reset all the beam pitch data.
4. Do SP2109-001 and enter "144".
• The "144" entry is only a starting point for the adjustment.
3 5. Do SP2109-003 (400 dpi Initial Setting) if you entered "0" in Step 2.

-or-
Do 2109-004 (600 dpi Initial Setting) if you entered "8" in Step 2.
6. Do SP2902 to print Test Pattern 12.
7. On the test pattern write 144, the value of SP2109-01.
8. Repeat Steps 2 to 7 and change the value of SP2109-001 for every execution (48, 96, 192,
240).
9. Check these test patterns. If the laser beam pitch is not correct, the image looks like a black
vertical stripe pattern (see the diagrams below).
For example, if the pattern made with the value "192" has fewer obvious stripes than the other print-
outs, the correct value is near 192.
10. Do Steps 2 to 7 to adjust the laser beam pitch position until thin lines are of uniform thickness
(no stripes should appear on the printout).
11. In Step 4, input a value estimated to be correct (e.g., if 192 was the closest, try 182), then
do Steps 5 and 6, then if necessary go back to Step 3 and try another value.
After adjusting the laser beam pitch for 400 dpi, adjust it for 600 dpi, using the same procedure as
for 400 dpi (use the SP modes for 600 dpi). Laser beam pitch for 600 dpi should be 24 ~ 48 more
than for 400 dpi.

Parallelogram Image Adjustment
Parallelogram Image Adjustment

Do the following procedure if a parallelogram prints while adjusting the printing registration or printing
margin using the trim pattern.
The following procedure should be done after adjusting the side-to-side registration for each paper tray
station. Use SP2902-010 (Print T Pattern – Trim Area) to determine whether a parallelogram image ap-
pears. If the parallelogram pattern appears, perform the following procedure.
1. Laser unit [A]

6. Adjust the laser unit position by turning the adjustment cam. (See the illustration above.)
7. Tighten the adjustment bracket.
8. Print the trim pattern again with SP2902-010 to check the image. If the results are not sat-
isfactory, repeat this procedure until the pattern is perfectly rectangular.

SC Code Descriptions
• If a problem concerns a circuit board, disconnect and reconnect the connectors and then test the
machine. Often a loose or disconnected harness is the cause of the problem. Always do this before
you decide to replace the PCB.
• If a motor lock error occurs, check the mechanical load before you decide to replace the motor or
sensors.
• When a Level “A” or “B” SC occurs while in an SP mode, the machine cannot display the SC number.
If this occurs, check the SC number after leaving the SP mode.
• The machine reboots automatically when the machine issues a Level “D” SC code. This is done for
Level “D” SC codes only.
• Never turn off the power switch when the power LED is lit or flashing.

Procedure 1
If the machine shows SC codes for HDD errors (SC860 ~ SC865) with SC 925, do the recovery procedures
for SC860 ~ SC865.
Procedure 2
If the machine does not show one of the five HDD errors (SC860 ~ SC865), turn the machine power off
and on. If this is not the solution for the problem, then initialize the NetFile partition on the HDD with
SP5832-011 (HDD Formatting – Ridoc I/F).
NetFiles: Jobs printed from the document server using a PC and DeskTopBinder
Before you initialize the NetFile partition on the HDD, tell the customer that:
• Received faxes on the delivery server will be erased
• All captured documents will be erased 4
• DeskTopBinder/Print Job Manager/Desk Top Editor job history will be erased
• Documents on the document server, and scanned documents, will not be erased.
• The first time that the network gets access to the machine, the management information must be con-
figured again (this will use a lot of time).
Procedure 3
If “Procedure 2” is not the solution for the problem, do SP5832-001 (HDD Formatting – All), then turn the
machine power off and on.
SP5832-001 erases all document and address book data on the hard disks. Ask the customer before you
do this SP code.
Procedure 4
If “Procedure 3” is not the solution for the problem, replace the HDD.

Switches fusing idling on/off. When on, printing will not start until enough time has elapsed so
the hot roller can reach optimum temperature. This ensures even heat on the hot roller.
Switch on if fusing on the 1st and 2nd copies is incomplete (this may occur if the room is cold.)
You must switch SP1103-1 ON before you set the fusing interval with SP1103-2.

1: Phase (hysterisis) control. Sets the upper and lower limits for the temperature; at the lower
1104 temperature the fusing lamp is on and at the higher temperature the fusing lamp is off.
Change this setting to “0” only if the user has excessive electrical noise or interference on the
power supply line. Such interference can cause voltage to drop when power is applied using
the ON/OFF control method.
Interference can be caused by the general poor quality of the power supply lines, or if the
machine is sharing a power supply with other electrical devices such as fluorescent lights. Before
changing this setting, make sure that the machine is connected to a power supply not shared
by other electrical equipment.
Note: Selecting Phase control (“1”) could cause the fusing temperature control board to emit
low pitched noise.

to make lots of copies that have a high proportion of black.
194

2210 ID Sensor
Pattern Interval
Sets the interval between ID sensor pattern prints for toner control. This setting allows adjustment
for customers who do not make many prints daily. Selecting zero cancels creation of the ID
sensor pattern.
001 [0 ~ 200 / 10 / 1 print step]
The ID sensor reads the sensor pattern and outputs this reading as Vsp and sends it to the CPU
where it is used to calculate Vref (Vsp/Vsg = Vref).
If the total count exceeds 10 during a print job, for example “15”, the pattern is created and
read at completion of the print job.
Large Job
Sets the interval between ID sensor pattern prints with the halftone pattern added. The ID sensor
reads the halftone pattern and outputs it as Vsm to the CPU. The Vsm value is used in the
5
calculation Vsm/Vsg to adjust the power to the LD.
002 [2 ~ 999 / 200 / 1 print step]
This SP executes at 200 prints (or at the adjusted count) regardless of whether the print job has
completed. This method of adjusting the power output and the amount of light emitted by the
LD ensures standard quality images by ensuring that prints do not become faint, slows the
deterioration of the OPC drum over time, and reduces scatter.

Transfer Cleaning Blade Forming
[0 ~ 30/ 3 / 1 sheets]
Applies a pattern of toner to the transfer belt at a defined interval between sheets on the transfer
2964 belt in order to reduce friction between the belt surface and the cleaning blade.
Under conditions of high temperature and high humidity, the density control feature may reduce
the amount of toner, which also reduces the amount of toner on the surface of the transfer belt.
With less toner on the belt, the friction between the belt and the blade increases, and could
cause the blade to bend or scour the surface of the belt.

Sets a time limit for issuing the toner near end warning on the operation panel. The time may
2975 need to be shorter for customers who run especially large print jobs (working at night, for
example) to ensure earlier warning of the toner near end condition so toner out does not interrupt
a long job.
0: Normal end detection (90 sheets after near-end detected (SP2213)
T Bottle On Cnt Toner Bottle Total On Time
2976 [0 ~ 2,000,000 / 0 / 1 ms step]

Displays the total ON time of the toner supply motor, calculated from when the toner bottle was
replaced. Use this to check that the toner end count (SP2975) is working properly.
202

When SP2975 is set to any value other than “0”, this value is displayed when it matches the
setting of SP2975. When SP2975 is set to “0”, SP2976 is disabled. SP2976 is automatically
set to zero by toner end recovery.)
Charge Counter
[0 ~ 1000000 / 0 / 1 step]
Sets the number of pages to print after toner and carrier initialization before the charge input is
2980 increased to compensate for deterioration over time in the polarity of the carrier.
The strength in the polarity of the carrier in the toner will eventually decrease and cause lower
charge output. Setting the charge output to increase after a specified number of copies can
compensate for this effect.

This SP is the IPv6 gateway address referenced on the Ethernet

or wireless LAN (802.11b). The IPv6 address consists of a total
158 IPv6 Gateway 128 bits configured in 8 blocks of 16 bits each. These notations
can be abbreviated. See "Note: IPV6 Addresses " below this
5 table.
This SP allows you to confirm or set the setting for the stateless
161 IPv6StatelessAut automatic setting function used by either the Ethernet or Wire-
less LAN (802.11b).
Note: IPV6 Addresses

Ethernet and the Wireless LAN (802.11b) reference the IPV6 "Link-Local address + Prefix Length". The
IPV6 address consists of 128 bits divided into 8 blocks of 16 bits:
aaaa:bbbb:cccc:dddd:eeee:ffff:gggg:hhhh:
The prefix length is inserted at the 17th byte (Prefix Range: 0x0~0x80). The initial setting is 0x40(64).
For example, the data
2001123456789012abcdef012345678940h
is expressed:
2001:1234:5678:9012:abcd:ef01:2345:6789: prefixlen 64
However, the actual IPV6 address display is abbreviated according to the following rules.
- Rules for Abbreviating IPV6 Addresses -

1. The IPV6 address is expressed in hexadecimal delmited by colons (:) with the following characters:
0123456789abcdefABCDEF
2. A colon is inserted as a delimiter every 4th hexadecimal character.
fe80:0000:0000:0000:0207:40ff:0000:340e
3. The notations can be abbreviated by elminating zeros where the MSB and digits following the MSB
are zero. The example in "2" above, then, becomes:
224

fe80:0:0:0207:40ff:0:340e
4. Sections where only zeros exist can be abbreviated with double colons (::). This abbreviation can be
done also where succeeding sections contain only zeros (but this can be done only at one point in
the address). The example in "2" and "3" above then becomes:
fe80::207:40ff:0:340e (only the first null sets zero digits are abbreviated as "::")
-or-
fe80:0:0:0:207:40ff::340e (only the last null set before "340e" is abbreviated as "::")

information (user codes and passwords) for system managers and users as well.
Note:
• Be sure to cycle the machine off and on after you execute this SP code.
046
• Once this SP has been executed, a message on the screens of applications that use the
address book will prompt users that the address book is being updated. This prevents the
machine from issuing SC870.
• The machine initializes to determine if the address book is stored on the HDD or on an SD
card. In order for the machine to determine whether to recognize an address book on the
HDD or the SD card, the machine must be cycled off and on once more to determine
whether the machine should recognize the address book on the HDD or the SD card.

not stored on the document server.
Local storage (document server). Totals (jobs, pages, etc.) for the document
server. The L: counters work differently case by case. Sometimes, they count
jobs/pages stored on the document server; this can be in document server
L: Local mode (from the document server window), or from another mode, such as
from a printer driver. Sometimes, they include occasions when the user uses
a file that is already on the document server. Each counter will be discussed
case by case.

Test Pattern Printing

Test pattern printing is a two-step operation. First, you must do SP2902 to select the pattern that you want
to print. If you select any pattern other than "0:None" under SP2902, this sets the printer in the Test Pattern
Print mode. Second, you must do SP5990 005 to print the pattern.
• You can select any selection under SP5990 to print the selected pattern. However, SP5990 005
(Diagnostic Report) is recommended because it prints only one page. If you select "001", for example,
several copies of the same pattern may print.
• The printer will remain in the Test Pattern Print mode until you leave the SP mode or the printer power
is turned off and on. (If you leave and reenter SP mode or turn the printer off/on, this automatically
reselects "0:None" for SP2902.)
• The normal SMC report lists done with SP5990 will not print until the printer has been released from
the Test Pattern Print mode.

Using Debug Log
Using Debug Log

This machine provides a debug log feature that allows the service technician to save and retrieve error
information for analysis.
Every time an error occurs, debug information is recorded in RAM but this information is lost when the
machine is switched off and on.
To capture this debug information, the Save Debug Log feature provides two main features:
• Switching on the debug feature so error information is saved directly to the HDD for later retrieval.
• Copying the error information from the HDD to an SD card.
When a user is experiencing problems with the machine, follow the procedures below to set up the machine
so the error information is saved automatically to the HDD. Then attempt to duplicate the problem so the
error data will be stored.

More About Debug Log
SP5857-015: SD to SD (Any)
This SP copies the log on an SD card (the file that contains the information written directly from shared
memory) to a log specified by key number. The copy operation is executed in the log directory of the SD
card inserted in the same slot. (This function does not copy from one slot to another.)
Each SD card can hold up to 4 MB of file data. Unique file names are created for the data during the copy
operation to prevent overwriting files of the same name. This means that log data from more than one
machine can be copied onto the same SC card.
This command does not execute if there is no log on the HDD for the name of the specified key.
SP5857-016: Make HDD LogFile

5 This SP creates a 32 MB file to store a log on the HDD. However, this is not a completely empty file. The
created file will hold the number “2225” as the SCS key number and other non-volatile information.
Even if this SP is not executed, a file is created on the HDD when the first log is stored on the HDD, but this
operation takes time. This creates the possibility that the machine may be switched off and on before the
log can be created completely.
If you execute this SP to create the log file beforehand, this will greatly reduce the amount of time required
to acquire the log information and save onto the HDD. With the file already created on the HDD for the
log file, the data only needs to be recorded; a new log file does not require creation.
To create a new log file, execute SP5857-011 to delete the debug log data from the HDD and then execute
this SP (SP5857-016).
SP5857-017: Make SD Log File

This SP creates a 4 MB file to store a log on an SD card. However, this is not a completely empty file. The
created file will hold the number “2225” as the SCS key number and other non-volatile information.
Even if this SP is not executed, a file is created on the SD card when the first log is stored on the SD card,
but this operation takes time. This creates the possibility that the machine may be switched off and on before
the log can be created completely.

6. Details
Printing Process Overview
Drum Charge
The charge roller [1] gives a negative charge to the organic photoconductive (OPC) drum. The charge
remains on the surface of the drum because the OPC layer has a high electrical resistance in the dark.
Laser Exposure
The image data is projected onto the drum by two laser beams [2], which form an electrostatic latent image
on the drum surface. The amount of charge remaining as a latent image on the drum depends on the laser
beam intensity, controlled by the BICU.
Development
The magnetic developer brush on the development roller [3] contacts the latent image on the drum. Toner
particles are electrostatically attracted to the areas of the drum surface where the laser reduced the negative
charge on the drum.
Image Transfer
Paper is fed into the area between the drum surface and the transfer belt [4] at the proper time to align it
with the image on the drum. The transfer bias roller applies a high positive charge to the reverse side of
the paper through the transfer belt. This positive charge pulls the toner particles from the drum surface onto
the paper while the paper is electrostatically attracted to the transfer belt.
308

Printing Process Overview
Separation
Paper separates from the drum as a result of the electrical attraction between the paper and the transfer
belt. Pick-off pawls [5] help separate the paper from the drum.
ID Sensor
The ID sensor [6] measures the reflectivity of the pattern formed by the laser on the surface of the drum.
This output signal is used for toner supply control and also measures the drum surface reflectivity, which is
used for charge roller voltage control.
Cleaning
The drum cleaning blade [7] removes any toner remaining on the drum surface after the image is transferred
to the paper.
Quenching
Finally, the light from the quenching lamp [8] electrically neutralizes the charge on the drum surface.

Laser Exposure
Laser Exposure Overview
1 LD unit 6 Synchronization detector
2 Cylindrical lens 7 BTL (Barrel Toroidal Lens)
3 Polygonal mirror 8 F-theta mirror
4 Shield glass 9 Toner shield glass
5 Mirror
This machine uses two laser diodes to produce electrostatic images on an OPC drum. The laser diode unit
converts image data from the BICU board into laser pulses, and the optical components direct these pulses
to the drum. To produce a high quality copy image, these are 256 gradations for the laser power.
The output path from the laser diode to the drum is shown above. The LD unit outputs two laser beams to
the polygon mirror through the cylindrical lens and the shield glass.
310

Laser Exposure
Each surface of the polygon mirror reflects two full main scan lines. The laser beams go to the F-theta mirror,
mirror, and BTL (barrel toroidal lens). Then these laser beams go to the drum through the toner shield glass.
The laser synchronization detector determines the main scan starting position.
• The front door and upper right door (transfer door) are equipped with safety switches that automat-
ically shut down the laser unit when either door is opened.
Auto Power Control (APC)
The LD driver on the LDDR drives the laser diode. Even if a constant electric current is applied to the laser
diode, the intensity of the output light changes with the temperature. The intensity of the output decreases
as the temperature increases.
In order to keep the output level constant, the LDDR monitors the electrical current passing through the
photodiode (PD). Then it increases or decreases the current to the laser diode as necessary, comparing it
with the reference level. This auto power control is done just after the machine is turned on and during
printing while the laser diode is active.
The reference levels are adjusted on the production line. Do not touch the variable resistors on the LDDR 6
in the field.
Dual-Beam Writing
This LD unit employs two laser diodes [A] (LD) and [B] (L2). Each face of the polygon mirror writes two
main scan lines, and twelve main scans are produced when the polygon mirror rotates once. This reduces
311

6. Details
polygon motor rotation speed, reduces noise generated by the polygon motor, and reduces the frequency
of the image data clock.
The two laser beams follow the path: collimating lenses [C] > prism [D] >polygon mirror [E].
6
The two laser beams arrive on the drum surface about 2 mm apart in the main scan direction and about
0.06 mm apart (at 400 dpi) in the sub scan direction. The two-mm difference in the main scan direction
allows the machine to detect the laser synchronization signal for each beam.
Laser Beam Pitch Change Mechanism
When the LD positioning motor [A] turns, the metal block [B] in contact with the LD unit housing [C] moves
up and down and changes the position of L2 (L1 does not move).
312

Laser Exposure
Both LD unit positions are at fixed distances from the LD unit home position sensor [D].
Usually, the LD unit moves directly to the proper position. However, when the number of times that the
resolution has changed reaches the value of SP2109 05, the LD unit moves to the home position, and this
re-calibrates the LD unit positioning mechanism.
LD Safety Switches
To ensure personal safety and to prevent the laser beam from inadvertently switching on during servicing,
power to the laser diode is switched off when the front cover or upper right cover is opened. Four safety
switches are installed in series on the LD5 V line from the power supply unit (PSU) via the BICU board.

Drum Drive Mechanism
The drive from the main motor [A] is transmitted to the drum [B] through a series of gears, a timing belt [C],
and the drum drive shaft [D].
The main motor has a drive controller, which outputs a motor lock signal when the rotation speed is out of 6
the specified range. The flywheel [E] on the end of the drum drive shaft stabilizes the rotation speed (this
prevents banding and jitter on copies).
Drum Pawls
The pick-off pawls [A], mounted in the holders [B] on the drum and in contact with the drum, strip paper
from the drum if it has not yet separated. The gears [C] are removable, and the positions of the holders can
be adjusted.

New PCDU Unit Detection
New Unit Detection Mechanism
This printer uses a push-switch to trigger the initialization of a new PCU.
316

When the PCU is removed from the maintenance kit, the trip lever is in the down position [1]. After the new
PCU is installed in the machine, the trip lever is forced into the up position [2]. This triggers the initialization
procedure shown below (Please refer to the flow chart below, "What Happens When a New Unit Is
Detected".)
This event is triggered only once after the new PCU is installed. The trip lever will remain in the up position
for the remainder of the service life of the PCU, regardless of how many times the PCU is removed and
reinstalled in the machine.
• When a new PCU is removed from its box, handle it carefully to avoid hitting the trip lever and moving
it accidentally out of its down position.
• If the trip lever on a new PCU is not down when the PCU is inserted in the machine for the first time,
the machine will not detect the PCU as a new unit and the initialization sequence will not occur.

[D], bias plate [E], and the rear roller bushing [F] to give the drum surface a negative charge of –800 V.

Charge Roller Voltage Correction
Correction for Environmental Conditions
The voltage transferred from roller to drum could vary with the temperature and humidity around the drum
charge roller. The lower the temperature or humidity, the higher the applied voltage required.
The ID sensor measures the effects of ambient conditions, and any small change in drum potential caused
by changes in temperature/humidity is reflected in the amount of toner transferred to the drum.
This measurement is done immediately after the ID sensor pattern for toner density control. After creating
ID sensor pattern [A], another pattern [B] is made. To do this, the LD switches off, the charge roller voltage
drops, and the drum potential is reduced to –600 V. At the same time, development bias returns to –550
V. The drum potential is now slightly higher than the development bias, so only a very small amount of toner
320

Drum Charge
transfers to the drum. The ID sensor measures the density of pattern [B], and Vsdp, the output voltage, is
compared with Vsg which was read from the bare drum at the same time.
Correction for Paper Width and Thickness (By-pass Tray only)

The by-pass tray can be used for non-standard paper narrower than sizes accepted by the paper trays.
Thicker paper, OHP sheets, etc. can also be loaded in the by-pass tray but adjustments must be performed
with the SP modes listed below in order to avoid jams and quality problems.
SP Mode SP Name
SP2001-01 Charge Roller Bias Adjustment Default: –1,480 V
SP2001 02 ID Sensor Pattern Default: -200 V
SP2309-01 Paper Lower Width [a] Width limit. Default: 150 mm
SP2309-02 Paper Upper Width [b] Width limit. Default: 216 mm
SP2914-01 Process Ctrl Set – C alpha Adjust 10 V/step. Default: +150 V

6
SP2914-02 Process Ctrl Set – C beta Adjust 10 V/step. Default: 0
The way that these SP modes are used is shown below.
For example, with the default settings, if the paper width fed from the by-pass tray is 100 mm, the charge
roller voltage will be –1,480 + 150 V.
ID Sensor Pattern Production Timing
An ID sensor pattern is created on the drum:

• Every time the system is powered up
• After every 10 prints
321

6. Details
• After 100 prints

• After 200 prints
After 10 prints
The ID sensor reads the sensor pattern and outputs this reading as Vsp and sends it to the CPU where it is
used to calculate Vref (Vsp/Vsg = Vref).
• This number of prints can be adjusted with SP2210-01 (Pattern Interval – ID Sensor).
• When the number of prints exceeds 10 during a print job, the ID sensor pattern is not created and
read until after the print job completes.
After every 100 prints
• This number of prints can be adjusted with SP2973-01.
• When the number of prints exceeds 100 during a print job, the ID sensor pattern is not created and
read until after the print job completes.
• At this time, a halftone pattern is added to the standard ID sensor pattern. The reading from this pattern,
Vsm, is used with Vsg (Vsm/Vsg) to calculate the value to be used to determine the amount of LD
(laser diode) power adjustment required. This method improves consistent greyscale reproduction,
6 slows the deterioration of the OPC drum, and reduces scatter.
After every 200 prints
• The halftone pattern is added to the standard ID sensor pattern every 200 prints. This interval can be
changed with SP2210-02 (Large Job).
• When 200 prints is reached, even if in the middle of a job, the ID sensor pattern will be made. For
example, if the job contains 1,100 sheets, the ID sensor patterns will be made every 200 sheets, and
at the end of the job.
• When the front door of the machine is opened and closed
• The halftone pattern is added to the standard ID sensor pattern at this time also.
The following SP codes are also used for grayscale control. Refer to the SP code table for full details.

Development
Drive Mechanism
The feed/development motor [A] drives the development roller [B] through the gears and the paddle roller
gear [C]. 6
The drive shaft engages and disengages the paddle roller gear when the development unit is inserted into
and removed from the machine.
• The development drive gears are helical gears, quieter than normal gears.
Developer Mixing
The dual mixing roller consists of the outer paddle [A] and the inner auger [B].
325

6. Details
The outer paddle moves developer to the front Ê and supplies it to the development roller. Developer that
spills off by the doctor blade Ë passes through the holes [C] in the outer paddle, and is transported to the
rear Ì by the inner auger.
While the dual mixing roller is moving the developer, some developer also passes back to the development
unit through the holes in the bottom of the paddle roller Í. New toner from the toner bottle and recycled
toner from the toner collection coil both enter the development unit at [D].
Development Bias
Development Bias Mechanism

Black areas of the latent image are at a low negative charge (about 150 V) and white areas are at a high
negative charge (about –950 V).
To attract negatively charged toner to the black areas of the latent image on the drum, the high voltage
supply board [A] applies a bias of –540 volts to the development roller throughout the image development
process. The bias is applied to the development roller shaft [B] through the bias terminal spring [C] and
bias terminal [D].
The development bias voltage (–540 V) can be adjusted with SP2201 (Development Bias).
Correction for Paper Width and Thickness (By-pass Tray only)

The by-pass tray can be used for non-standard paper narrow than sizes accepted by the paper trays.
Thicker paper, OHP sheets, etc. can also be loaded in the by-pass tray but adjustments must be performed
with the SP modes listed below in order to avoid jams and misfeeds.

Toner Supply
Toner Bottle Replenishment Mechanism
6
When the toner bottle is installed in the bottle holder [A], pin [B] slides up the side of the PCU [C], pulling
out the toner shutter [D]. When the toner bottle holder lever [E] is returned to its original position, the cap
[F] pulls away and is kept in place by the chuck [G].
The toner bottle holder lever [E] cannot be lowered:
• Until a toner bottle is installed in the holder. This prevents toner falling out of the holder unit as a result
of lowering the handle with no toner bottle installed.
• Until the holder and bottle have been pushed into the machine completely and locked in place. Instruct
the customer to always follow the bottle replacement instructions of the new decal attached to the
toner bottle.
The toner bottle has a spiral groove which rotates the bottle to move toner to the development unit. When
the bottle holder unit is pulled out, the chuck [G] releases the toner bottle cap and the toner shutter [D]
closes and blocks the opening.
328

Development
Toner Supply Mechanism
The toner supply motor [A] rotates the toner bottle [B] and the mylar blades [C].
Toner falls into the toner bottle holder, and the toner supply mylar blades [C] transfer the toner to slit [D].
Installing the PCU opens the shutter [E]. The toner falls into the development unit through the slit.
Toner Density Control

There are two modes for controlling and maintaining constant toner supply: sensor control (both direct and
indirect) and image pixel count control. The mode can be changed with SP2208-01 (Toner Supply Mode).
329

6. Details
• The factory setting is sensor control mode. Image pixel count mode should only be used temporarily
until a defective TD or ID sensor can be replaced.
Sensor Control Mode

In the sensor control mode, the amount of toner required to print the page is calculated by the CPU. The
CPU adds up the image data value of each pixel and converts the sum to a value between 0 and 255.
(255 would mean a completely black page.)
The machine must vary toner supply for each print in order to maintain the correct amount of toner in the
developer and to account for changes in drum reflectivity due to changes in temperature and humidity. The
CPU uses data from the TD sensor and ID sensor to determine whether or not the toner supply motor should
be switched on and to calculate how long it should remain on in order to supply more toner to the mixture
in the development unit.
TD Sensor
6 When new developer of standard toner concentration is installed, namely 20 g of toner per 500 g of
developer (4.0% by weight), the TD sensor must be set to its initial setting of 4.0 V with SP2801. This initial
setting is used as the toner supply reference voltage or Vref. For every print cycle, the TD sensor directly
checks the toner density in the developer mixture, and after 10 copies these 10 readings are averaged
and this value becomes TD sensor output voltage Vt (10).
The machine compares Vt (10) with Vref. If Vt (10) is greater than Vref, the toner concentration in the
development unit judged to be low. When Vt (10) is detected to be greater than Vref 20 times, then this
indicates that the toner concentration is consistently low, Vref is incremented by 0.1 V, and the conditions
are checked again. The result of this check determines the value of K, the toner supply rate coefficient,
which is one of the factors that is used in the toner supply motor on-time calculation.
ID Sensor
In addition to comparing Vt(10) from the TD sensor and Vref after every 10 copies, the ID sensor (located
at the lower right area of the drum) checks both the reflectivity (Vsg) and the pattern on the drum (Vsp)
created by the laser diodes and charge roller. If the reflected light is too strong, this indicates that toner is
low and toner is added to the development unit. (The frequency of these checks can be adjusted with
SP2210.).
Image Pixel Count Mode

This mode should only be used only as a temporary measure while waiting for replacement parts, such as
a TD sensor. This mode controls the toner supply amount using the same method for determining the toner
bottle motor on time. However, the values that were in effect when the toner density control mode was
330

Development
changed over to image pixel count mode with SP2208-01 (Toner Supply Mode) remain in effect and
cannot be changed.
Toner Near End/End Detection
Standard Method for Toner Near-End/End Condition Detection

The toner near-end condition is detected based on the Vt(10) output from the TD sensor.
• If the difference between Vref (toner supply reference voltage) and Vt (10) is less than or equal to –
0.45, then toner concentration is judged as very low and K (the toner supply coefficient) is set to 0.25,
the machine enters the toner near end condition and the machine switches on the toner supply motor.
• If a difference greater than –0.45 is detected, then toner concentration is judged as low but the
machine does another test by comparing Vref and Vt (10).
• If the machine determines that Vt (10) is greater than Vref 40 times, the toner supply motor switches
on and remains on for twice the time that Vt (10) was greater than Vref. If the toner concentration is
still low, then the machine enters the toner near end condition.
The final toner end is detected using the ID sensor. If the ID sensor detects that the ID sensor pattern is very
6
light (Vsp drops below 2.0 V), then the sensor triggers the toner end condition.
If Vsp is less than 2.0 V, the density of the ID sensor pattern is very light, so the machine detects the toner
end condition. However, if Vsp remains higher than 2.0 V but 90 copies have been made after toner near
end was determined, the machine enters the toner end condition.
• The number of copies between toner near-end and toner end can be changed with SP2213. The
default is 90 copies.
Adjustable Near-end Warning Method

By storing a value in SP2975, a near-end warning can be set up to appear on the LCD when the toner
supply motor has rotated for a certain amount of time from after a new toner bottle was installed. This allows
the user to be prepared much earlier than just 90 prints to change the bottle. Refer to the SP table for more.
Toner End Recovery
If the front door is opened and then closed while a toner near end/end condition exists, the machine will
attempt to recover. When the front door is closed, the toner supply motor turns on to supply toner. The
machine checks the TD sensor output 2 seconds after the main motor turns on (Vtp), and the sensor is
checked again every 1 second (Vtp1)
331

6. Details
The machine detects the toner concentration using Vref, Vt (10), Vtp, and Vtp1. If the toner concentration
is still too low, the toner supply motor remains on for another 10 seconds while the machine checks Vt. If
toner concentration is judged to be at the standard level, then the toner near end/end condition is cancelled
and K (toner supply coefficient) is reset. If toner concentration has not reached the standard level, the toner
supply motor rotates continuously until it does (maximum motor on time is 16 seconds) and then it will switch
off.
Toner Supply with Abnormal Sensors
The TD sensor is checked every copy. If the readings from the TD sensor become abnormal during a copy
job, the machine holds the GAIN factor constant (GAIN is normally calculated from TD sensor readings)
to allow toner supply to vary with only pixel count for the rest of the copy job. Then at the end of the copy
job, an SC code is generated and the machine must be repaired.
The ID sensor is checked every 10 copies. If readings become abnormal, an SC code is generated and
the machine must be repaired. If this happens during a copy job, Vref is not changed, the copy job is
allowed to finish, and then the SC code is generated.
6 If spare parts are not available, the technician can use SP2-208-1 (Toner Supply Mode) to temporarily
put the machine in image pixel count mode. (See Section 5 Service Tables.)

Drum Cleaning and Toner Recycling
Drum Cleaning and Toner Recycling

Drum Cleaning
This machine employs a counter blade system. After the image is transferred to paper, a cleaning blade
[A] removes any toner remaining on the drum. The toner collection coil [B] carries excess toner to the toner
collection plate [C].
The collar [D] on the cleaning blade bracket contacts the outer rim of cam gear [E], which moves the
cleaning blade side to side. This side-to-side movement disperses accumulated toner to prevent early blade
edge wear at one location.
The drum reverses about 5 mm after every print job to remove particles on the edge of the cleaning blade.
333

6. Details
Toner Recycling

Toner collected by the toner collection coil [A] is transported to the opening [B]. This toner falls into the
development unit with new toner coming from the toner bottle. The paddle roller [C] mixes the collected
toner with the new toner.
• A screen filter [D] has been added to strain out paper dust and other foreign matter.

Each paper tray, which employs the FRR system, can hold 500 sheets. Two relay sensors, positioned above
each set of relay rollers, detect paper jams. A selection dial allows you to select the setting for the size of
the paper loaded in the tray.
335

6. Details
Paper Feed Drive
The feed/development motor [A] drives the pick-up and feed mechanism of both the upper and second
6 paper feed stations through gears and the paper feed clutches [B].
When the paper feed clutch turns on, the pick-up roller, paper feed roller, and separation roller start rotating
to feed the paper. The paper feed clutch stays on until shortly after the registration sensor [C] actuates.
Pick-Up and Separation Roller Release Mechanism
When the paper tray [A] is not inside the machine, the separation roller [B] is away from the paper feed
roller [C] and the pick-up roller [D] stays in the upper position.
336

Paper Feed
When the paper tray is set into the machine, it pushes the release lever [E]. This causes the pick-up roller
[D] to go down and the separation roller [B] to move up and contact the paper feed roller.
Paper Lift
6
The paper size switch [1] detects when the paper tray [2] is set in the machine, and the tray lift motor [3]
rotates, and the coupling gear [4] on the tray lift motor engages the pin [5] on the lift arm shaft [6]. Then
the tray lift arm [7] lifts the tray bottom plate [8].
337

6. Details
When the paper tray is set in the machine, the pick-up roller [9] lowers. When the top sheet of paper
reaches the proper height for paper feed, the paper pushes up the pick-up roller, and the actuator [10]
on the pick-up roller supporter activates the paper height sensor [11] to stop the tray lift motor.
6 After several paper feed cycles, the paper level gradually lowers and the paper height sensor is de-
activated. The tray lift motor turns on again until this sensor is activated again.
When the paper tray is removed from the machine, the tray lift motor coupling gear disengages the pin on
the lift arm shaft, and the tray bottom plate then drops under its own weight.
Paper End Detection
If there is paper in the paper tray, the paper end feeler [A] is raised by the paper stack, and the paper end
sensor [B] is deactivates.
338

Paper Feed
When the paper tray runs out of paper, the paper end feeler drops into the cutout [C] in the tray bottom
plate and the paper end sensor is activated.
Paper Registration
The registration drive roller [A] and idle roller [B] correct the skew of the paper to ensure that the leading
edge of the paper is positioned correctly at the drum. The paper feed/development motor [C] drives the
registration mechanism.
The registration sensor [D] is just before the registration rollers. When the leading edge activates the reg-
istration sensor, the registration clutch is switched off and the registration rollers stop turning. However, the
relay clutch [E] remains on slightly longer. This delay allows more time for the paper to press against the
registration rollers and buckle slightly to correct any skew. The registration sensor also detects misfeeds.
Next, the registration clutch [F] and the relay clutch turn on at the correct time to align the paper with the
image on the drum. The registration rollers then feed the paper to the image transfer section.
Two new dust blades have been added around the registration roller. The idle roller dust blade [G] cleans
the registration idle roller. This dust blade has a small dust box that collects paper dust that must be emptied
periodically.
The registration roller dust blade [H] cleans the registration roller. For details about how to remove and
clean these new parts, see Section “3 Replacement and Adjustment”.
Paper Size Detection
The paper size switch includes four microswitches. Actuators behind the paper size dial actuate the sensors.
339

6. Details
Each paper size has its own actuator, with a unique combination of notches. To determine the paper size,
the CPU reads which switches the actuator has turned off.
The CPU disables paper feed from a tray if the paper size cannot be detected. If the paper size actuator
is broken, or if there is no tray installed, the printer control board recognizes that the paper tray is not
installed.
When the paper size actuator is at the “*” mark, the paper tray can be set up to accommodate one of a
wider range of paper sizes by using a menu setting on the machine’s operation panel.

The by-pass unit is directly driven by the machine through gear [A].
When the print key is pressed, the pick-up solenoid [B] turns on and the pick-up roller [C] moves onto the

By-Pass Paper Size Detection
The paper size sensor board [A] monitors the paper width.
The rear side fence is connected to the terminal plate. The pattern for each paper width is unique. Therefore,

Transfer Belt Drive Mechanism
6
After the main motor switches on during printing, the transfer belt contact clutch [A] switches on after a
specified interval and the cam [F] makes a half-turn to raise the contact lever [E] and bring the transfer belt
[D] into contact with the drum.
The actuator [C], on the same axis as the cam, and the transfer belt position sensor [B] detect whether the
drum and transfer belt are in contact.
When the main motor is off, or when the ID sensor pattern is being measured, the transfer belt unit separates
from the drum. The ID sensor pattern must not be transferred to the belt. Also, the transfer belt and drum
must not remain in contact for too long, to prevent contamination of the drum with oil or other foreign
material from the transfer belt.
351

6. Details
Transfer Belt Unit Contact Mechanism
6 The belt contact and release mechanism consists of the belt contact clutch [A], cam [B], and contact lever
[C]. The belt contact clutch turns on and the cam attached to the clutch rotates half a complete rotation.
The contact lever, riding on the cam, is lifted up and the springs [D] push the belt into contact with the drum.
The transfer belt position sensor [E] detects the home position of the cam (this is when the belt is away from
the drum). The belt must be released from the drum between copy jobs in order to prevent the ID sensor
pattern from being rubbed off and to prevent contamination of the drum from the surface of the belt.
352

Image Transfer and Paper Separation Mechanism
6
When the registration clutch switches on to align the leading edge of the paper [A] with the image on the
drum [B], the transfer belt is [C] is away from the drum.
353

6. Details
At the designated time after the main motor switches on, the transfer belt contact clutch switches on and
the transfer belt touches the drum at [D].
6 When the paper enters the gap between the belt and the drum, the high voltage supply board [E] applies
a high positive current to the belt to transfer the image to the paper.
After receiving the image from the drum, the paper is fed by the belt. The paper moves to the end of the
transfer belt unit, where it separates from the belt as the belt curves away. Then the paper moves on to the
fusing unit.
354

Transfer Belt Charge
Transfer Belt Charge Mechanism
The high voltage supply board [A] applies a positive current to the transfer belt [B] through the terminal
block [C], terminal plate [D], and the bias roller [E].
The high voltage supply board adjusts the current to the roller to keep a small but constant current flow to
ground through the belt, paper, and drum. If this current is not kept constant, efficiency of toner transfer
and paper separation will vary with paper thickness, type, environmental condition, or changes in transfer
belt surface resistance.
Correction for Paper Width and Thickness

A range of SP modes is available in order to adjust the machine so it can handle papers of non-standard
size and thickness.
For paper width, there are two thresholds. The factory settings are 150 mm (5.9”) and 216 mm (8.5”).
Below 216 mm, the transfer current can be increased. By default, the current is multiplied by 1.2 for the
main machine paper trays. For paper widths below 150 mm, the transfer current can be set higher, but by
default it is kept the same as the current for paper widths below 216 mm. The higher current allows for the
355

6. Details
tendency of the current to flow directly from the transfer belt to the drum and not through the paper which
could cause an insufficient amount of toner to transfer to narrow width paper.
Thick paper must be fed from the by-pass tray because SP modes are available only for the by-pass tray
in order to accommodate thick paper. By default, the current for paper narrower than 216 mm is 1.5 times
the normal current.
This illustration shows the SP modes, which control these currents. The base transfer current (‘current’ in the
diagram) depends on SP 2-301. This is different for various parts of the image, and is different for the by-
pass tray; see the next page for details.
Currents Applied to Leading Edge, Image Areas, and By-Pass Feed

Transfer current can also be adjusted for the leading edge and the image area, and for by-pass feed. The
timing for starting to apply leading edge current, for the switchover from leading edge current to image
area current, and for switching off at the trailing edge can also be changed.
The table below lists the SP modes you can use to adjust these settings.

Scraped off toner and paper dust falls into the toner collection tank [B] in the transfer belt unit. This toner
is not recycled. When the toner overflow sensor [C] detects toner overflow, the toner overflow indicator
lights. Up to 999 copies can be made before the toner overflow condition shuts down the machine.

Fusing Drive
6
The fusing exit motor [A] drives the fusing unit through the gears [B] and also drives the paper exit rollers
[C] through a gear and a timing belt [D].
Fusing Drive Release Mechanism
359

6. Details
The fusing unit drive release mechanism automatically disengages the fusing unit drive gear [A] when the
right door [B] is opened.
When the right cover is opened, the actuator plate [C] pulls release wire [D]. The wire pulls the fusing drive
gear bracket [E] and the fusing unit drive is disengaged.
Fusing Entrance Guide Shift Mechanism
The entrance guide [A] has two holes on each side to adjust for paper thickness to prevent creasing.
Normally, the left screw hole [C] on each side is used.
For thin paper, use screw holes [B] to move the entrance guide to the left. This setting allows more direct
access to the gap between the hot and pressure rollers, and prevents thin paper from buckling against the
hot roller which can cause blurring at the leading edge of the copy.
360

Exit Guide Plate and De-Curler Rollers
The exit guide plate [A] also functions as a pressure roller stripper. The exit guide plate can be moved in 6
order to remove jammed paper.
Stacking has been improved by mounting a face-curl correction mechanism at the paper exit roller.
Two de-curler rollers [B] and [C] have been added under the exit roller [D] to correct the curl that paper
acquires during transport through the fusing unit.
Pressure Roller
The pressure springs [A] apply constant pressure between the hot roller [B] and the pressure roller [C]. The
applied pressure can be changed by adjusting the position of the pressure springs. The left position [D] is
361

6. Details
the normal setting, and the right position [E] increases the pressure to prevent insufficient fusing by the fusing
unit.
Cleaning Mechanism
6 The cleaning roller [A], in constant contact with the pressure roller [B], collects toner and paper dust from
the surface of the pressure roller. Because the cleaning roller is metal, it can collect adhering matter better
than the pressure roller, which is coated with Teflon.
Fusing Temperature
Fusing Temperature Components
362

The fusing unit has two fusing lamps: the first fusing lamp (center: 650W) [A] heats the center of the fusing
roller, and the second fusing lamp (ends: 550W) [B] heats both ends of the hot roller. This arrangement
ensures even heat on all surfaces of the roller.
In order to control the temperature of the roller, two high response thermistors are attached to the unit, one
near the center [C] and one at the end [D] of the hot roller.
Fusing Temperature Control
There are two types of temperature control: On/off control (Default), and Phase control.
Either mode can be selected with SP1104 (Fusing Temperature Control).
After the machine is powered on, the CPU checks the ac frequency for 500 ms, in case phase control is
selected later for the temperature control, and then switches on the fusing lamp.
As soon as both the center and end thermistors detect the print ready temperature (also known as the “re-
load” temperature) , the machine can operate. The “reload” temperature is 30°C below the fusing
temperature (this depends on SP1105-05, 06). As soon as the thermistors detect the fusing temperature,
the CPU switches the lamps off but frequently switches on/off again in order to maintain the fusing tem-
perature.
363

6. Details
Fusing Idling Temperature

If copies are not sufficiently fused soon after the power switch is turned on, fusing idling should be enabled
with SP1103-01.
When fusing idling is enabled, it is done when the temperature reaches the re-load temperature. The re-
load temperature can be adjusted with SP1105-05, 06.
In the opposite case, even if fusing idling is disabled, it is done if the temperature at power-up ≤ 15°C
The fusing idling time is as follows.
Fusing Idling Mode

Temperature at power-on
0: Disabled 1: Enabled SP1103-01
15°C or less 30 s 30 s
SP1103-02
Higher than 15°C Not done 30 s
6 Overheat Protection
If the hot roller temperature becomes greater than 250°C, the CPU cuts off the power to the fusing lamp,
and SC543 (Fusing Overheat Error) will be displayed.
Even if the thermistor overheat protection fails, there is a thermostat in series with the common ground line
of the fusing lamp. If the temperature of the thermostat reaches 210°C, the thermostat opens, removing
power from the fusing lamp. At the same time, the machine stops operating. At this time, SC542 (Fusing
Temperature Warm-up Error) will be displayed.
364

Energy Save Mode
Energy Save Mode

If the printer remains idle for the selected time interval, the machine automatically enters the energy saver
mode and switches off the fusing lamps to reduce power consumption.
The customer can select the idle time interval or switch the energy saver mode off. The Energy Saver selector
setting is in the System menu, which can be accessed at the printer operation panel:
[Menu]> System> Energy Saver> E. Saver On/Off (*On)
[Menu]> System> Energy Saver> E. Save Timer (*1 minute)
[Menu] Settings
Energy Saver On/Off On (default)
Energy Saver Timer *1 (default), 5, 15, 30, 45, 60 minutes
• After the machine remains idle for the specified time, the CPU switches off the fusing lamps.
• The machine leaves the energy saver mode and returns to normal operation when any key on the
operation panel is pressed, when the printer receives a print job from the computer, or after the printer 6
is switched off and on.
• The time from receiving the print start command to making the first print is longer than when powering
up from normal standby mode.
For details, see the Operating Instructions.
