1. DRUM CHARGE
In the dark, the charge corona unit gives a uniform negative charge to the
organic photoconductive (OPC) drum. The charge remains on the surface
of the drum because the OPC drum has a high electrical resistance in the
dark.
2. EXPOSURE
An image of the original is reflected to the drum surface via the optics
assembly. The charge on the drum surface is dissipated in direct
proportion to the intensity of the reflected light, thus producing an
electrical latent image on the drum surface.
3. ERASE
The erase lamp illuminates the area of the charged drum surface that will
not be used for the copy image. The resistance of the drum in the
illuminated areas drops and the charge on those areas dissipates.
4. DEVELOPMENT
Positively charged toner is attached to the negatively charged areas of
the drum, thus developing the latent image. (The positive triboelectric
charge is caused by friction between the carrier and toner particles.)
5. IMAGE TRANSFER
Paper is fed to the drum surface at the proper time so as to align the copy
paper and the developed image on the drum surface. Then, a strong
negative charge is applied to the back side of the copy paper, producing
an electrical force which pulls the toner particles from the drum surface to
the copy paper. At the same time, the copy paper is electrically attracted
to the drum surface.
6. PAPER SEPARATION
A strong positive dc charge is applied to the back side of the copy paper
via a discharge plate, reducing the negative charge on the copy paper
and breaking the electrical attraction between the paper and the drum.
Then, the stiffness of the copy paper causes the paper to separate from
the drum surface.
7. CLEANING
The cleaning blade scrapes the toner off the drum. The collected toner is
recycled.
8. QUENCHING
Light from the quenching lamp electrically neutralizes the drum surface.

DRUM
1. DRUM
The OPC (Organic Photoconductor) drum used in this copier is small in
diameter (30 mm), ensuring good paper separation. An OPC drum has the
following characteristics.
1. The drum is able to accept a high negative electrical charge in the dark.
(The electrical resistance of a photoconductor is high in the absence of
light.)
2. It dissipates the electrical charge when exposed to light.
(Exposure to light greatly increases the conductivity of a photoconductor.)
3. The amount of charge dissipated is in direct proportion to the intensity of
the light. That is, where stronger light is directed to the photoconductor
surface, a smaller voltage remains on the drum.
4. An OPC drum is less sensitive to changes in temperature (when
compared to selenium F type drums).
5. During the drums life, drum residual voltage gradually increases and the
photoconductive surface becomes worn. Therefore, some compensation
for these characteristics is required.

This copier uses a single wire scorotron to charge the drum. The corona wire
[A] generates a corona of negative ions when the high voltage supply unit
applies a negative voltage. The stainless steel grid plate [B] ensures that the
drum coating receives a uniform negative charge as it rotates past the corona
unit.
The exhaust fan [C] causes a flow of air above and through the charge
corona section. This prevents an uneven build-up of negative ions that can
cause uneven image density.
An ozone filter [D], which absorbs ozone (O3) generated by the charge
corona, is located beside the exhaust fan. The ozone filter decreases in
efficiency over time as it absorbs ozone. The ozone filter should be replaced
every PM cycle (45 k copies).

Pads [A] move along the charge corona wire as the wire cleaner knob [B] is
manually slid in and out.
The cleaner pad bracket [C] is connected to the wire cleaner knob. When the
knob is pulled out, the pads move into contact with the corona wire as shown,
since the casing [D] is narrower away from the home position.
The pads move away from the wire when the wire cleaner knob is fully
inserted and the pad bracket is pushed back to the home position.
After copier installation, the key operator should be instructed to use this
mechanism when copies have white streaks or uneven image density.
Instruct the operator to firmly push the pad bracket into the home position.
Poor copy quality will result if the cleaning pads remain in contact with the
charge corona wire.

The main board supplies +24 V to the high voltage supply board at CN102-7.
After the ! key is pressed, the CPU drops CN102-5 from +5V to LOW.
This activates the charge corona circuit which applies a high negative voltage
of approximately 5 k volts to the charge corona wire. The corona wire then
generates a negative corona charge.
The grid plate limits the charge voltage to ensure that the charge does not
fluctuate and that an even charge is applied to the entire drum surface. The
grid plate is connected to ground through a zener diode in the high voltage
supply unit. The grid plate drains any charge in excess of 910 V, which is
discharged to ground through the zener diode.

This copier has eight standard reproduction ratios and a zoom function. The
operator can also change the reproduction ratio in one-percent steps from
50% to 200%. Stepper motors are used to change the positions of the lens
and 4th/5th mirrors to enlarge/reduce the image across the page. Changes in
reproduction ratio down the page are achieved by changing the scanner
speed.
The CPU monitors the temperature around the optics through a thermistor
which is located on the scanner frame. When the temperature reaches 40C,
the optics cooling fan [K] starts rotating to draw cool air into the optics cavity.
The fan operates until the temperature drops below 38C.
Additionally, a thermofuse on the 1st scanner provides back-up overheat
protection. It opens when the temperature reaches 128C and cuts ac power
to the exposure lamp.
A blue filter is located just after the lens to improve the reproduction of red
areas of the original on copies.

The auto image density (ADS) sensor [A], a photodiode, is mounted on the
upper front frame. The sensor cover has a hole in it to allow light to fall
directly onto the sensor.
Sampling starts 6 millimeters from the leading edge of the original and
continues for 11.5 millimeters from the leading edge of original in full size
mode. These lengths "a" and "b" will vary depending on the selected
reproduction ratio. The lengths "a" and "b" for each reproduction ratio are
calculated as follows:
For every original in ADS mode, the photosensor circuit converts the light
intensity into a voltage. The detected voltage is amplified and sent to the
main board. If less light is reflected from the original (the image is darker), the
sensor outputs a lower voltage. The CPU compares the maximum ADS
output voltage with the standard ADS reference voltage and compensates
the copy image density by changing the development bias voltage in
accordance with the difference. The standard ADS reference voltage (2.5
0.1 V) is generated by SP 56. Details about changes to the development bias
voltage are explained in "Development Bias for Image Density Control".

The main board controls the exposure lamp voltage through the ac drive/dc
power supply board. The exposure lamp voltage is based on the base lamp
voltage and various correction factors. The method of control is different
depending on whether the image density is manually selected or the auto
image density mode is selected.
The exposure lamp voltage is determined by the following factors:

The light intensity may decrease because of dust accumulated on the optical
parts. Additionally, the drum sensitivity gradually decreases during the drums
life. This may cause dirty background on copies. To compensate for this, VL
corrections 1 and 2 are done.
The exposure lamp voltage is increased by two steps at the set copy count
interval (a step is +2.0 V for 230 V machines, and +1 V for 120 V machines).
The table below shows the relationship between the SP setting and the copy
interval.

5) VL Correction 2 Factor
VL correction 2 compensates for dust on the lens and mirrors 1 to 3, but is
independent of the drum condition.
The ADS sensor receives the light reflected through the 1st, 2nd and 3rd
mirrors from the white plate located under the middle of the left scale. The
photosensor circuit converts this light intensity into a voltage. The CPU stores
this voltage in memory as the white plate reference voltage. This is done
every time SP56 (ADS reference voltage adjustment) is done, before
sampling starts for the ADS sensor adjustment.
Every 500 copies, the machine reads the intensity of light reflected from the
white plate and compares it with the white plate reference voltage.
If the measured voltage difference is more than 0.1 volt, +2 steps will be
added to the exposure lamp setting as the VL correction 2 factor.
The sum of VL correction factors 1 and 2 cannot exceed +40 steps.
VL correction factors 1 and 2 are automatically reset every time the light
intensity is adjusted with SP48. (SP56 must be done immediately after SP48;
see Service Remarks for details.)

When the main motor turns on, the development roller [A] and two agitators
[B] and [C] start turning.
There are permanent magnets in the development roller which attract the
developer particles (which are about 50 m in diameter) to the roller. The
turning sleeve of the development roller carries the developer past the doctor
blade [D] which trims the developer to the desired thickness.
The development roller sleeve continues to turn, carrying the developer to the
drum [E]. When the developer brush contacts the drum surface, the
negatively charged areas of the drum surface attract and hold the positively
charged toner. In this way, the latent image is developed.
The development roller is given a suitable negative bias to prevent toner from
being attracted to the non-image areas on the drum which may have a
residual negative charge. The bias also controls image density.

The CPU checks the voltage output from the automatic ID circuit. This circuit

output voltage, which corresponds to the maximum reflectivity of the original.
The CPU then determines the proper base bias level by comparing this
voltage (read from the original) with the standard ADS reference voltage.

The toner end detection system determines when to drive the toner bottle
replenishment mechanism (see Toner End Detection). The toner supply
mechanism transports toner from the bottle to the development unit. The
toner bottle has a spiral groove [K] that helps move toner to the development

A toner density sensor (TD sensor) [A] is used for toner density control.
The TD sensor is located under the 1st agitator [B]. The developer being
conveyed by the 1st agitator passes over the top of the sensor. As the toner
in the developer is consumed during development, the toner to carrier ratio
changes, resulting in a change in the magnetic permeability of the developer.
This in turn is converted to a corresponding voltage. The CPU monitors the
voltage to control the toner supply mechanism.
When new developer is installed, and SP66 (TD Sensor Initial Setting) is
done, the machine starts idling for developer initialization. During developer
initialization, the CPU adjusts the TD sensor control voltage so that the TD
sensor outputs 1.9 0.1 V for the toner to carrier ratio of new developer
(4.0% by weight). This voltage is used as the standard TD sensor voltage.

ms and stores the second highest voltage of every 240 ms period. The
voltages stored during the two seconds are averaged, and then the average
is used as the TD sensor output value for that detection period. The TD
sensor output value is used to determine the toner supply clutch on time.
Then an appropriate amount of toner is added by the toner supply motor (as
described in Toner Supply Amount). The TD sensor is monitored for
two-second intervals until the last original scan is finished. Unlike a toner

Note that when 2, 3, or 4 is selected, the machine will not perform the toner
near-end/or toner end detection. Normally, SP30 should always be kept at
the default setting. The following pages describe the toner supply mode
settings in detail.
6.5.2 Detect Supply Mode
In Detect Supply mode, the CPU monitors the TD sensor voltage, which
depends on the toner to carrier ratio in new developer. As the toner in the
developer is consumed, the TD sensor output voltage increases.
The TD sensor voltage is compared with the standard voltage (known as the
Target Toner Sensor Voltage), and toner is supplied when the TD sensor
output is higher than this target voltage.
The machine has two ways of calculating the target toner sensor voltage
(either the initial TD sensor setting is used, or a value can be input using
SP53); the method used depends on SP30. The toner supply amount can
also be changed using SP31 or 32.

The toner removed from the drum falls onto the toner collection coil [A]. The
drum gear rotation is directly transmitted to the toner collection coil drive gear.
As the coil rotates, the toner moves from rear to front until it reaches the
toner recycling belt [B]. The paddles of the belt, which is driven by the toner
collection coil shaft, transports the toner into the developer, and the toner is
recycled.

This copier has one paper feed station and a by-pass feed table.
The paper feed station uses a paper tray [A] which can hold 500 sheets. The
by-pass feed table [B] can hold 80 sheets.
The paper tray uses two semicircular feed rollers [C] and corner separators.
The semicircular feed rollers make one rotation to drive the top sheet of the
paper stack to the relay rollers [D]. The paper tray has two corner separators,
which allow only one sheet to feed. They also hold the paper stack. When the
paper tray is drawn out of the machine, the spring pressure is released, and
the tray bottom plate drops. In addition, there is no need to press the bottom
plate down when putting the tray back in.
The by-pass feed table uses a feed roller and friction pad system to feed the
top sheet of paper to the registration rollers.
In humid environments, copy paper may crease as it comes out of the fusing
unit. The optional tray heater [E] is available as a service part to keep copy
paper dry.

The capacity of this tray is higher than usual for a corner separator type.
Because of this, there are two springs to lift the bottom plate.
As the tray is pushed into the machine, shutter [A] under the tray pushes
against projection [B]. As the shutter slides past the projection, the shutter
rotates, which forces the main lift spring [C] to pull the bottom plate lever [D].
The secondary lift spring [E] also pulls the bottom plate lever (this is
described below).
The tension applied to the main lift spring is always the same. However, the
secondary spring is only used when wider paper is installed, to lift the extra
weight of the paper stack. The tension applied to the secondary lift spring
depends on the paper width. Below a certain threshold width, tension is not
applied. Above this width, the wider the paper, the more tension is applied.
To apply spring tension for wider paper, projection [F] stops against the end
of rail [G]. When this happens, lever [H] swings out in the direction shown
above, which stretches the spring as the tray is pushed in. The side fence
position affects the orientation of [F]; wider paper causes [F] to contact [G]
earlier, leading to greater spring tension when the tray has been pushed all
the way in.
For narrow paper, the secondary lift spring is not needed. The side fence
orients projection [F] so that it slides past the rail as the tray is pushed into
the machine, and the spring stays slack.
The bottom plate stopper [I] rests on the bottom plate [J]. It stops the bottom
plate at the maximum height. When the tray is getting empty, the corner
separators [K] start to rise, and continue to rise as the amount of paper in the
tray decreases, so that the paper is always at the correct height.

Through several gears and a timing belt, main motor rotation is transmitted to
the tray paper feed clutch gear [A] and the relay roller clutch gear [B].
-Feed rollersThe tray paper feed clutch gear is on the same shaft as the semicircular
feed rollers [C]. After the ! key is pressed, the tray paper feed clutch [D] is
energized for 250 milliseconds to release the stopper [E]. Then the drive of
the main motor is transmitted, and the feed rollers make one complete
rotation to feed the top sheet of paper which is enough for the leading edge
of the paper to be caught by the relay rollers [F]. The feed rollers stop when
the stopper drops back into the notch at the end of one complete turn.
-Relay rollersThe relay roller clutch gear is on the same shaft as the relay rollers. The
rotation timing of the relay rollers is controlled by the relay roller clutch [G].
The CPU energizes the relay roller clutch after the ! key is pressed (at the
same time as the tray paper feed clutch). Paper is fed from the relay rollers to
the registration rollers [H].

This machine uses a feed roller [A] and friction pad [B] mechanism, with drive
from the main motor [C] transmitted when the by-pass feed clutch [D] turns
on. The friction pad prevents all but the top sheet from feeding. Therefore,
during paper feed, the top sheet of paper is separated from the stack and fed
to the registration rollers.
Before placing paper on the by-pass feed table, the user must lower the
by-pass feed table by using the lever [E]. This is to ensure that the paper is
placed between the friction pad and the feed roller. Then, before starting to
copy, it must be put back up to move the paper stack into contact with the
feed roller.
When there is no paper on the by-pass feed table, the paper end feeler [F]
drops into the cutout in the by-pass feed table and the by-pass feed paper
end sensor is activated.

Main motor rotation is transmitted to the registration roller clutch gear [A]
through several gears and a timing belt. When the registration clutch [B] is
energized, the rotation of the clutch gear is transmitted to the lower
registration roller [C].
The registration sensor [D], which is positioned just before the registration
rollers, controls the relay roller clutch stop timing. The relay roller clutch stays
on for 130 milliseconds after the leading edge of the paper actuates the
registration sensor. The CPU then turns off the relay roller clutch. This delay
allows time for the paper to press against the registration rollers and buckle
slightly to correct skew.
The CPU energizes the registration clutch at the proper time to align the
paper with the image on the drum.
The registration sensor is also used for paper misfeed detection.
The paper dust mylar [E] on the upper registration roller [F] removes paper
dust before the paper reaches the transfer/separation unit.

There is a side fence stopper mechanism for both the front and rear side
fences.
If the tray is closed with excessive force after loading paper, paper may come
over the rear side fence, because the fence is deformed by the weight of the
paper leaning against it. As a result, skewing or paper jams may occur. To
prevent this, a side fence stopper mechanism has been added to the rear
side fence.
The release levers [A] each have a stopper which contains teeth like those
on a gear. The guide rails [B] also have teeth. When the release lever is
pushed, the gear teeth release each other and the side fences can be moved.

paper end sensor [D].
The paper end actuator is in contact with the lever [E]. When the tray is
drawn out, the lever turns as shown by the arrow in the diagram. Then the
lever pushes up the actuator. As a result, the feeler rotates upwards. This

Just after the main switch is turned on, the CPU checks these sensors for
any jammed paper.
During the copy cycle, the CPU performs four kinds of misfeed detection. The
following explains jam detection timing for copying A4 sideways paper.
A (1): Checks whether the registration sensor is actuated within 2.01 seconds
after the ! key is pressed.
A (2): Checks whether the exit sensor is actuated within 4.97 seconds after
the ! key is pressed.
A (3): Checks whether the copy paper has passed through the registration
sensor 7.45 seconds after the ! key is pressed.
A (4): Checks whether the copy paper has passed through the exit sensor
7.80 seconds after the ! key is pressed.
NOTE: A (1) and A (2) are detected from the lead edge of the copy paper.
A (3) and A (4) are detected from the trail edge of the copy paper.
The detection timing for A (3) and A (4) will vary with the

unit from overheating.
The hot roller strippers [E] separate the copy paper from the hot roller and
direct it to the exit rollers. The exit sensor [F] monitors the progress of the

A219D537.wmf
The main board monitors the fusing temperature through a thermistor. It uses
the zero cross signal generated by the ac drive/dc power supply board to
control the applied power accurately.
Normally, the voltage applied to the lamp is the full duty cycle of the ac
waveform. However, through SP29, fusing power can be set to phase control
mode. (Phase control is used only if the customer has a problem with
electrical noise or interference.)
A219
2-54
SM
IMAGE FUSING
When the main switch is turned on, the main board starts to output a trigger
pulse, which has the same timing as the zero cross signal, to the ac drive/dc
power supply board. This trigger pulse allows maximum ac power to be
applied to the fusing lamp. When the operating temperature is reached, the
CPU stops outputting the trigger pulse (the trigger stays HIGH) and the fusing
lamp turns off.
A219D538.wmf
The main board sends the fusing lamp trigger pulse (LOW active) to the ac
drive/dc power supply board, which provides ac power to the fusing lamp at
the falling edge of each trigger pulse. The trigger pulse goes HIGH when the
main board receives the zero cross signal.
The amount of time that power is applied to the fusing lamp depends on the
temperature of the hot roller.
The trigger pulse (LOW part) is wider [C1] and power is supplied for longer
[D1] when the hot roller temperature is lower. It is narrower [C2] and power is
supplied for a shorter time [D2] when the hot roller is near the operating
temperature.

SERVICE REMARKS
1. SERVICE REMARKS
1.1 GENERAL CAUTIONS
1. To prevent physical injury, keep hands away from the mechanical drive
components when the main switch is on (especially during the warm-up
cycle).
If the ! key is pressed before the copier finishes the warm-up cycle,
the Start indicator starts blinking and the copier starts making copies as
soon as the warm-up cycle is completed.
2. Before disassembling or assembling any parts of the copier, make sure
that the power cord is unplugged.
1. Always ensure the following when removing the imaging unit from the
copier.
Do not touch the drum surface with bare hands. When the drum
surface is touched with fingers or becomes dirty, wipe it with a dry
cloth.
Place the imaging unit on a clean and level place. Take care not to
scratch the drum from under the unit as there is no cover to protect it.
Cover the imaging unit with sheets of paper to prevent the drum from
being exposed to light.
Do not turn the imaging unit upside down. Toner and developer may
fall out from the unit.
2. Before pulling out the imaging unit, place a sheet of paper under the unit
to catch any spilled toner.
3. Never use alcohol to clean the drum; alcohol dissolves the drum surface.
4. Take care not to scratch the drum as the photoconductive layer is thin
and is easily damaged.
5. Never expose the drum to corrosive gases such as ammonia gas.
6. Store the imaging unit in a cool, dry place away from heat.
7. Do not touch the charge corona wire or the grid plate with bare hands. Oil
stains may cause uneven image density on copies.
8. Clean the charge corona wire by pulling on the wire cleaning knob.
9. Clean the charge grid with a blower brush (not with a cloth).

SERVICE REMARKS
1.3 OPTICS
1. Clean the exposure glass with glass cleaner and a dry cloth to reduce the
amount of static electricity on the glass surface.
2. Only use a clean soft cloth to clean the mirrors and reflectors.
3. Only use a blower brush to clean the 6th mirror and the lens.
4. Do not touch the following parts with bare hands:
1) Reflectors
2) Exposure Lamp
3) Mirrors and Lens
5. Do not change the cutout position of the reflectors as they are adjusted at
the factory.
6. Always replace the 1st scanner unit as an assembly, as the matching of
each set of exposure lamp and reflectors is performed at the factory.
7. Only use the scanner timing belts when manually moving the scanner
units.

SERVICE REMARKS
8. Whenever cleaning or replacing the optics, all the following actions must
be done in order.
1) Optics cleaning
2) Open SP33 (Image Bias Adjustment - Manual ID Mode) and return the
setting to the normal value if it has been changed.
3) SP48 (Light Intensity Adjustment) - see the SP mode table for details

SERVICE REMARKS
1.7 OTHERS
1. When replacing the main board, remove the EEPROM (IC112) from the
old main board and place it on the new main board. Then install the new
main board in the copier.
2. After installing a new main board with a new EEPROM (IC112), the Clear
All Memory (SP99) procedure must be performed. (Do not perform SP99
if you have placed the old EEPROM on the new main board.)
3. Never perform SP99 (Clear All Memory) except for the following two
cases:
a) When the copier malfunctions due to a damaged EEPROM.
b) When replacing the EEPROM.
4. Whenever SP99 (Clear All Memory) is performed, the drum and
developer must be replaced with new ones. Otherwise, copy quality might
be seriously affected.

PROGRAM MODES
2. PROGRAM MODES
2.1 BASIC OPERATION
1. Component
This copier is equipped with two program modes. One is the Service Program
(SP) Mode for factory and field technician usage, and the other is the User
Program (UP) mode for the user. Both program modes have a different
access procedure, but all the UP mode functions can be accessed from the
SP mode.
To be able to reset a service call (E5) condition using SP mode, the SP mode
can be accessed while the error condition exists. The error code will not be
displayed in the copy counter during these conditions.
2. Operation
To access these program modes, certain keys must be pressed after turning
on the main switch. After accessing, select the required mode number and
perform the procedure needed for that function. It is possible to move on to
the next required mode without exiting each time.
To exit these modes, turn the main switch off/on.
3. Display
The Copy Counter is used to display the program mode number. The
Magnification Ratio display is used to display the current value.
When the Copy Counter is blinking, and the dot is lit, the machine is ready
to accept a program mode number. (The program mode number is
displayed when you input it.) The Magnification Ratio display is blinking at
this time.
When the Copy Counter stops blinking, and the dot starts blinking, the
machine is ready to accept an adjustment value, and it may be displaying
the current adjustment value on the Magnification Ratio display.
4. Notes
1. With the exception of SP57, all copies made inside the program
modes are made with ID level 4 (center value).

- Recovering the machine after a memory reset WARNING: If SP99 is performed, all the software counters for process
control and the TD sensor initial setting data are reset. As a
result, the old drum and the old developer cannot be used any
more. Otherwise, dirty background and/or toner scattering will
appear on copies sooner or later because proper process control
will not be applied to the drum.

The grid voltage and charge corona current are carefully adjusted at the
factory. Any adjustment out of the adjustment standard will result in
overtoning, toner scattering, dirty background, or light image density
problems. The grid voltage and charge corona current adjustment
should be done only when replacing the power pack or to correct
certain problems with image density after checking all other possible
causes.

POWER DISTRIBUTION

A662D500.wmf
The document feeder uses two dc power levels: +24 volts, and +5 volts.
When the main switch is turned on, the DF transformer receives the wall
outlet ac power through the ac drive board and outputs 25 volts ac to the DF
main board. Then, the dc power supply circuit on the DF main board converts
the 25 volts ac input to +24 volts and +5 volts.
+24 volts is used by the DF motor, the pick-up solenoid, and the feed clutch.
+5 volts is used by other electrical components.

SM
BASIC OPERATION
5. BASIC OPERATION
When the main switch is turned on, the DF CPU sends the "DF installed"
signal to the copier CPU. Receiving this signal, the copier CPU recognizes
that the document feeder is installed and sends the "DF confirmed" signal to
the DF CPU.
When originals are placed on the original table, the Insert Original indicator
turns off and the DF CPU sends the "original set" signal to the copier CPU to
inform that the originals have been set.
When the Start key is pressed, the copier CPU sends the "feed-in" signal to
the document feeder. On receipt of this signal, the DF CPU energizes the DF
motor, then the pick-up solenoid and feed clutch to feed in the bottom sheet
of the original stack onto the exposure glass. The pick-up solenoid, and the
feed clutch remain energized until the originals leading edge reaches the
registration sensor. The DF motor turns off shortly after the originals trailing
edge passes the registration sensor. Then, the DF motor pauses and
reverses for a moment to align the edge of the original with the scale.
Document
Feeder A662
Then the scanner starts to move, (scanner start timing does not depend on
the progress of the original through the DF; it starts at a fixed time after the
Start key is pressed). When the scanner reaches the return position, the
copier CPU sends the "original change" signal to the DF CPU in order to feed
out the current original and feed in the next original.

Feeder A662
After setting the originals on the original table, the originals contact the feeler
[A] of the original set sensor and cause the feeler to move out of the sensor.
The DF CPU then sends the original set signal to the copier CPU to inform it
that the document feeder will be used. When the Start key is pressed, the
pick-up solenoid [B] is energized. The original stack is then pressed between
the pick-up lever [C] and pick-up roller [D]. The rotation of the pick-up roller
advances the bottom original.

The feed roller [A] and the friction belt [B] are used to feed in and separate
the originals [C]. Only the bottom original is fed because the friction belt
prevents any other originals from feeding.
Original feed starts when the pick-up lever [D] presses the original stack and
the rotation of the pick-up roller [E] advances the bottom original of the stack.
The feed roller moves the original past the friction belt because the driving
force of the feed roller is greater than the resistance of the friction belt. The
friction belt prevents multiple feeds because the resistance of the friction belt
is greater than the friction between original sheets.

The DF motor [A] drives the feed roller [B], the pick-up roller [C], the relay
rollers [D], and the transport belt roller [E] via timing belts and a gear train.
The feed roller and the pick-up roller are controlled by the feed clutch [F], but
the relay rollers and the transport roller are directly driven by the DF motor.
The idler rollers [G] on the feed roller shaft are free from the shaft.
When the Start key is pressed, the DF motor is energized and the relay
rollers and transport belt roller start turning. 100 milliseconds after the DF
motor starts turning, the pick-up solenoid and the feed clutch are energized.
The pick-up and feed rollers then start turning and carry the original between
the relay rollers and the idler rollers. The pick-up solenoid and the feed clutch
are de-energized when the originals leading edge passes through the
registration sensor.
To feed the second original, the DF motor starts rotating when the scanner
reaches the return position. (The copier CPU sends the original change
signal to the DF CPU.) At this time, the transport belt starts carrying the first
original on the exposure glass to the exit roller. The timing for when the
pick-up solenoid and the feed clutch are energized for the second original
depends on the length of the first original detected by the registration sensor.

The DF motor remains energized to deliver the original to the exposure glass
until a certain number of pulses (10 to 25 pulses) after the originals trailing
edge passes through the registration sensor. Then, the DF motor pauses and
reverses for 15 pulses to align the edge of the original with the scale.

The exit rollers are driven by the DF motor through a gear train, the transport
belt roller, the transport belt [A], the transport belt roller [B], and the exit roller
drive belt [C]. When the DF CPU receives the original change signal from the
copier CPU, the DF motor starts turning. Simultaneously, the transport belt
carries the original to the exit rollers [D] and the exit rollers take over the
original feed-out.

The DF motor is a 24 volt dc motor. When the CPU receives the feed signal
from the copier, the CPU outputs the ON signal and the Forward signal to the
gate IC. On receipt of the forward signal from the gate IC, the driver IC
outputs 24 volts to CN117-1 and 0 volts to CN117-2. This causes the DF
motor to start turning in the forward direction.
Document
Feeder A662
Within 10 to 25 pulses after the originals trailing edge passes through the
registration sensor, the CPU stops sending the ON signal and the Forward
signal. The DF motor stops turning. Then the CPU outputs the ON signal and
the reverse signal for 15 pulses. Then the driver IC outputs 0 volts to
CN117-1 and +24 volts to CN117-2 to reverse the DF motor.

The above chart shows the original feed timing for the original size of A4
lengthwise or 8.5" x 11" and the misfeed detection timing.
The registration sensor is used for misfeed detection. If the DF CPU detects
a misfeed, the DF CPU lights the Original Misfeed indicator and sends the
original misfeed signal to the copier CPU. Then the copier CPU lights the
Check Paper Path and Misfeed Location (J0) indicators on the operation
panel.
When the main switch is turned on, the DF CPU checks the registration
sensor output for initial original misfeed.
During original feed-in, the DF CPU performs two kinds of original misfeed
detection:
1. Whether the registration sensor is actuated within 500 milliseconds after
the pick-up solenoid and the feed clutch turn on.
2. Whether the original has passed through the registration sensor 1,500
milliseconds after the registration sensor has been actuated.

BASIC OPERATION
4. BASIC OPERATION
- Clear Mode (PROOF MODE) When the main switch of the copier is turned on, the sorter automatically
assumes clear mode. In this mode, all copies are stacked in the first bin. The
sorter also assumes clear mode when interrupt mode is selected.
Sorter operation begins when the copier sends the paper feed signal to the
selected paper feed station. At this time, the roller drive motor energizes.
When the paper exits onto the sorter bin, the paper sensor is de-activated
and the roller drive motor is then de-energized. The copier main board
monitors the paper sensor through the sorter main board to check for paper
misfeeds.
- Sort Mode In this mode, all copies of the first original are delivered to separate bins
starting from the top. The copies of the second original are delivered to the
same bins, but starting from the bottom. The copies of the third original start
from the top and so on. At 400 milliseconds after the copy has gone through
the paper sensor, the bin drive motor turns on to advance the bins one step.
- Stack Mode In this mode, all copies of the first original are delivered to the first bin, all
copies of the second original are delivered to the second bin, and so on. At
400 milliseconds after the last copy of the original has gone through the
paper sensor, the bin drive motor turns on to advance the bins one step.

The exit rollers [A] take over paper transport from the copier. When the copier
sends the paper feed signal to the selected paper feed station, the exit rollers
start rotating. The exit rollers continue to rotate for 900 milliseconds after the
copy paper has gone through the paper sensor [B].
The roller drive motor [C] rotates the lower exit roller via the roller drive belt
[D]. The shaft of the lower exit roller is a cylindrical cavity type which rotates
around the transfer wheel shaft [E]. The paper sensor is positioned just in
front of the exit rollers. The paper sensor detects misfeeds in the sorter.

MISFEED DETECTION
SERVICE TABLES
7. MISFEED DETECTION
A657D505.wmf
In addition to being used for the exit roller drive timing, the paper sensor
checks for misfeeds in the sorter.
J1 - Paper Sensor On Check (A4 Sideways):
The copier CPU checks whether the paper sensor is actuated within 4.32
seconds after the registration clutch turns on.
J2 - Paper Sensor Off Check (A4 Sideways):
The copier CPU also starts a timing cycle to detect the paper sensor off
check after the registration clutch turns on. The misfeed detection timing is
6.71 seconds.
In misfeed condition, the "Check Paper Path" and "Misfeed Location"
indicators light and copier operation is disabled. To recover the sorter from
the misfeed condition, the sorter has to be slid away from the copier, the
misfed paper removed, and the sorter returned to its original position.

6.1 OVERVIEW
[E]
[D]
[A]
[B]
[F]
[C]
[G]
A245D500.wmf
There are two paper trays and a by-pass feed table [A].
The upper [B] and lower [C] paper trays each hold 250 sheets. The by-pass
feed table can hold 1, 10, or 80 sheets of paper, depending on the paper type.
The semicircular feed rollers [D] drive the top sheet of paper from the tray to
the registration rollers [E] through the relay rollers [F].
The tray has two corner separators (see [F] in the diagram in the "Paper Lift
Mechanism" section), which allow only one sheet to feed at a time. The
corner separators, along with the trays springs, also serve to set the height
of the paper stack.
When the tray is closed after the paper is loaded, the paper size actuator
located at the front right of the tray pushes the paper size sensor. This
informs the cpu what paper size is loaded in the tray and that the tray is in
place.
The by-pass feed table uses a feed roller and friction pad system to feed the
top sheet of paper to the registration rollers.
In humid environments, copy paper may crease as it comes out of the fusing
unit. The optional tray heaters [G] are available as service parts to keep copy
paper dry. It can be installed for both paper trays.

When the paper tray [A] is closed after paper is loaded, the release slider [B],
which is mounted on the bottom part of the tray, is pushed by the projection
[C] on the main frame and the release slider comes off the bottom plate hook
[D].
Once the release slider comes off, the bottom plate is raised by the pressure
springs [E] and the top sheet pushes up the corner separators [F]. This keeps
the stack of paper at the correct height.

Through several gears and a timing belt, main motor rotation is transmitted to
the tray paper feed clutch gear [A] and the relay roller clutch gear [B].
-Feed rollersThe tray paper feed clutch gear is on the same shaft as the semicircular
feed rollers [C]. After the ! key is pressed, the tray paper feed clutch [D] is
energized for 250 milliseconds to release the stopper [E]. Then main motor
drive is transmitted, and the feed rollers make one complete rotation to feed
the top sheet of paper, which is enough for the leading edge of the paper to
be caught by the relay rollers [F]. The feed rollers stop when the stopper
drops back into the notch at the end of one complete turn.
-Relay rollersThe relay roller clutch gear is on the same shaft as the relay rollers. The
rotation timing of the relay rollers is controlled by the relay roller clutch [G].
The CPU energizes the relay roller clutch after the ! key is pressed (at the
same time as the tray paper feed clutch). Paper is fed from the relay rollers to
the registration rollers.

The registration sensor and the exit sensor are used for misfeed detection. If
the CPU detects a misfeed, the Check Paper Path and the Location
indicators turn on.
Just after the main switch is turned on, the CPU checks these sensors for
any jammed paper.
During the copy cycle, the CPU performs four kinds of misfeed detection. The
following explains jam detection timing for copying on A4 sideways paper
from the upper paper tray unit.

IMAGE FUSING
7. IMAGE FUSING
1. Both the hot roller and pressure roller for the A245 are different from the
A219. To distinguish between the two types of roller, check the end of the
roller shaft as described below.
- A219 -
HOT ROLLER

PRESSURE ROLLER
- A219 -
A245D504.wmf
- A245 -
A245D506.wmf
A245D507.wmf
2. Due to the increase in copier CPM, the thickness of the metal core of the
hot roller has been increased for the A245 copier. This causes the ready
temperature to be higher, and the temperatures are as follows:
A245 copier
A219 copier
Also, to achieve the same warm-up time as for the A219 copier in the 230 V
machines, the fusing lamp wattage has been increased from 650 W to 760 W.
For the 120 V machine, the warm-up time specification is slightly longer than
for the A219, so the lamp is not changed.
3. FUSING IDLING (SP116)
Fusing idling can be selected with SP116. This mode should be used
when the copier has fusing problems with copies which are made soon
after warm up. This problem is most likely to occur in low temperature
locations where the wall outlet condition is also not stable. Please note
that when this mode is selected, copier warm-up will take a couple of
seconds extra, and the first copy time will not be within specification.
When the start key is pressed, fusing idling is performed for 2 seconds. If
the temperature of the fusing unit is below the operating temperature by
up to 10C, copying starts. If the detected temperature is more than 10C
lower than the operating temperature, fusing idling will continue until the
detected temperature reaches 180C. This will take 6 ~ 7 seconds longer
to warm up than if fusing idling is not used.

4. SERVICE TABLES
4.1 SERVICE PROGRAM MODE
The following SP modes were added:
1. The method for calculating the target TD sensor output (Target VT) has been
changed from previous models. The previous Target VT will be called VTref,
and its default value has been changed from 1.9 to 1.5V. The alpha and beta
corrections described below will be added to VTref. The new Target VT is then
calculated as:
Target VT = VTref + +
2. For toner density correction, SP37 (alpha correction) has been added as a new
SP Mode.
3. In addition, items 5 and 6 in the second table below have been added to SP38
(beta correction).
