3. Diagnostic aids
This chapter explains the tests and procedures to identify printer failures and verify repairs have corrected the
problem.
Diagnostics are built into the printer RIP card assembly and can be accessed from the printer operator panel.
Diagnostics Mode 1. Turn off the printer The Diagnostics Mode group contains the settings
2. Press and hold and . and operations used while manufacturing and
servicing the printer.
SeeDiagnostics mode on page 3-2 for more
information.
To run the printer diagnostic tests described in this chapter, you must put the printer in Diagnostic Mode.
Diagnostics mode
Entering Diagnostics mode:
Available tests
Select Exit Diagnostics to exit the Diagnostics mode. Resetting the Printer displays, the printer
performs a POR, and returns to normal mode.
MOTOR TESTS
The tests in this group allow you to test specific motors, and on some motors run them forward or reverse.
Once selected the name of the selected test appears on the operator panel.
3. If available, Forward and Reverse appear for selected tests.
To stop the test, press Back ( ) or Stop ( ).
PRINT TESTS
The purpose of the diagnostic Print Tests is to verify that the printer can print on media from each of the installed
input options. The content of the Print Test Page varies depending on the media installed in the selected input
source.
Check each Test Page from each source to assist in print quality and paper feed problems.
The purpose of this diagnostic function is to allow printing of the print quality test pages with the toner cartridge
lockout function disabled. The print quality pages consists of four pages. Page one contains a mixture of
graphics and text. Page two is gray with black boxes. Page three is solid black. The last page is blank. If duplex
is turned on, the pages are duplexed. The Print Quality Test pages are printed in English and print on the media
available in Tray 1.
The following is included in the DIAGNOSTICS version of the print quality pages:
HARDWARE TESTS
Panel Test
Button Test
DRAM Test
CACHE Test
Parallel Wrap (if available)
Serial Wrap (if available)
Panel Test
This test automatically toggles all pixels of the operator panel through every contrast level beginning with the
darkest and on to the brightest. This test continues until you press Stop ( ).
Button Test
The Button Test verifies the operation of the buttons on the operator panel. When you select Button Test, a
diagram of the operator panel appears on the panel. When you press a button on the operator panel, the X
appears on the corresponding diagram. When you release the button, the X disappears. Pressing Back ( )
or Stop ( ) cancels the test.
DRAM Test
The purpose of this test is to check the validity of DRAM memory, both standard and optional. The test writes
patterns of data to DRAM to verify that each bit in memory can be set and read correctly.
The test continues until all standard and optional DRAM is tested. Once the maximum pass count or fail count is
reached, the test is stopped, the power indicator is turned on solid, and the final results display. To stop the test
before completion, turn the printer off.
CACHE Test
P:###### represents the number of times the cache has passed and finished successfully. Initially
000000 displays with the maximum pass count being 999,999.
F:##### represents the number of times the cache has failed and finished with errors. Initially 0000
displays with the maximum fail count being 99,999. Initially only four digits appear, but additional
digits appear as needed.
Each time a test is completed, the number of passes and failures is incremented. If the test fails, the
message Failure displays for approximately three seconds, and the failure count increases by one.
The test continues until all of the printer processors cache has been tested. Once the maximum pass count or
fail count is reached, the test is stopped, the power indicator is turned on solid, and the final results display.
This test is used with a wrap plug to check operation of the parallel port hardware. Each parallel signal is tested.
Use Parallel Wrap for the standard parallel port or Parallel 1 Wrap if a parallel port is available by PCI slot 1.
1. Disconnect the parallel interface cable, and install the wrap plug (P/N 1319128).
2. Select HARDWARE TESTS from DIAGNOSTICS.
3. Select Parallel Wrap or Parallel 1 Wrap, from the HARDWARE TESTS menu.
The power indicator blinks green indicating the test is in progress. The test runs continuously until a
maximum number of tests is reached.
Parallel Wrap
P:###### F:####
P:###### represents the number of times the memory test has passed and finished successfully.
Initially 000000 displays with the maximum pass count being 999,999.
F:##### represents the number of times the memory test has failed and finished with errors. Initially
0000 displays with the maximum fail count being 999,999. Initially only four digits appear, but
additional digits appear as needed.
Each time the test finishes, the screen updates. If the test passes, the pass counter increases by 1,
however if the test fails, a message displays for approximately three seconds. Once the maximum count is
reached, the test stops. The power indicator goes on solid, and the final results display.
The serial wrap tests are used to check the operation of the serial port hardware using a wrap plug.
1. Disconnect the serial interface cable, and install the serial wrap plug
2. Select HARDWARE TESTS from DIAGNOSTICS.
3. Select Serial 1 Wrap or Serial 2 Wrap from HARDWARE TESTS.
The power indicator blinks green indicating the test is in progress. The test runs continuously until a
maximum number of tests is reached.

P:###### represents the number of times the memory test has passed and finished successfully.
Initially 000000 displays with the maximum pass count being 999,999.
F:##### represents the number of times the memory test has failed and finished with errors. Initially
0000 displays with the maximum fail count being 999,999. Initially only four digits appear, but
additional digits appear as needed.
Each time the test finishes, the screen updates. If the test passes, the pass counter increases by 1,
however if the test fails, a message displays for approximately three seconds. Once the maximum count is
reached, the test stops. The power indicator goes on solid, and the final results display.
To stop the test before completion, press Stop ( ). The message Serial Wrap x Test Canceled, and
the display returns to the HARDWARE TESTS menu.
DUPLEX TESTS
This test prints a duplex version of the Quick Test that can be used to verify that the correct placement of the top
margin on the back side of a duplex page. You can run one duplexed page (Single), or continue printing
duplexed pages (Continuous) until Stop ( ) is pressed.
Make sure either Letter or A4 is loaded in the default paper source. If the default source only supports
envelopes, then the Quick Test will be printed from Tray 1.
The single test stops automatically when a single duplex sheet is printed, and the continuous test continues until
you press Stop ( ).
This test is used to determine whether or not the duplex sensors and switches are working correctly. The test
allows you to actuate the duplex input sensor located in the back part of the duplex unit and the duplex exit
sensor located in the return paper path.
This test lets the servicer observe the paper path as media is feeding through the printer. A blank sheet of paper
feeds through the printer as the laser turns off during this test. The only way to observe the paper path is to open
the lower front door that is used to access the envelope or multipurpose feeder. The paper is placed in the output
bin.
This test is used to determine if the input tray sensors are working correctly. To run the Input Tray Sensor Test:

4. The servicer can manually actuate the selected sensor, and Open or Closed displays.
Press Back ( ) or Stop ( ) to exit the test.
Use these tests to verify that media can be fed to a specific output bin. Media is fed from the default input source
to the selected output bin. No information is printed on the media fed to the output bin because the printhead is
not engaged during this test. These tests can use any media size or envelope supported by the printer.
This test can be used to verify that the printer can feed media to the standard bin or any installed output options.
No information will be printed on the test pages, as the printhead is not engaged during the feed test. The media
feeds from the default paper source.
The test is continuous until Stop ( ) is pressed. Press Back ( ) to return to OUTPUT BIN TESTS.
These tests are used to determine if the output tray sensors are working correctly.
4. Each of the tests categories includes the individual sensors that can be manually actuated, and the display
shows Open or Closed.

5. Manually actuate the selected sensor, and Open or Closed displays.
FINISHER TESTS
Staple Test
This test verifies the staple mechanism by sending eight sheets of media from the printers default paper source
and stapling the sheets.
This test is used to verify whether or not media can be fed to a finisher output bin and punched. Eight sheets of
blank paper are fed from the default paper source and fed to the finisher output bins. Letter size paper is used for
the 3 hole test, and A4 media is used for the 4 hole test. Media is selected from the default tray.
During the test, no buttons are active, and the test cannot be stopped until the test is completed.
Feed Tests
This test is used to verify whether or not media can be fed to a finisher output bin. Eight sheets of blank paper
are fed from the default paper source and fed to the finisher output bins.
Note: This test can be run using any of the paper sizes supported by the printer.
During the test, no buttons are active and the test cannot be stopped until the test is completed.
This test can be used to verify whether or not the finisher sensors are working correctly.
This test is used to determine if the sensors located inside the printer are working correctly.
DEVICE TESTS
This test performs a non-destructive read/write on one block per track on the disk. The test reads one block on
each track, saves the data, and proceeds to write and read four test patterns to the bytes in the block. If the block
is good, the saved data is written back to the disk.
Disk Test/Clean
Warning: This test destroys all data on the disk and should not be attempted on a good disk. Also note that this
test may run approximately 1 hours depending on the disk size.
3. To exit the test immediately and return to the Device Tests menu, press Back ( ) or Stop ( ). To
continue with the test, press .
If is selected, the following screen displays and updates periodically indicating the percentage of test
completed.
Formatting Disk

Flash Test
This test verifies the functioning of the flash device by writing and reading data on the flash to test the flash.
Warning: This test destroys all data on the flash, because the flash is unformatted at the end of the test. To
reformat the flash, the servicer or the user must use FORMAT FLASH from the UTILITIES MENU.
3. To exit the test immediately and return to the Device Tests menu, press Back ( ) or Stop ( ). To
continue with the test, press .
The power indicator blinks while the test is running, and the message Flash Test Testing displays.
Once the test is complete, the power indicator turns on solid, and either the message Flash Test Test
Passed or Flash Test Test Failed displays.
PRINTER SETUP
Defaults
US/Non-US defaults changes whether the printer uses the US factory defaults or the non-US factory defaults.
The settings affected include paper size, envelope size, PCL symbol set, code pages, and units of measure.
Warning: Changing this setting resets the printer to factory defaults, and data may be lost. It cannot be undone.
Page Count
The permanent page count can only be viewed and cannot be changed.
Serial Number
Warning: Do not change these settings unless requested to do so by your next level of support.
Model Name
Configuration ID
The two configuration IDs are used to communicate information about certain areas of the printer that cannot be
determined using hardware sensors. The configuration IDs are originally set at the factory when the printer is
manufactured, however the servicer may need to reset Configuration ID 1 or Configuration ID 2 whenever the
system board is replaced. The IDs consist of eight hexadecimal characters, including 0 through 9 and A
through F.
Note: When the printer detects a Configuration ID that is not define or invalid, the following occurs:
The default standard model Configuration ID is used instead.
Configuration ID is the only function available in DIAGNOSTICS.
Unless the menu is in DIAGNOSTICS, Check Config ID displays.
To set the configuration ID:
Edge to Edge
When this setting is On, the text and graphics are shifted to the physical edges of the paper for all margins.
When the setting is Off, the normal margins are restored.
This setting adjusts the amount of time the strobe is sampled in order to determine if the valid data is available
on the parallel port. The range of values are from -4 to 6, and the default is 0 for Par S Strobe Adj,
Par 1 Strobe Adj, and Par 2 Strobe Adj. After adjustment of 1 increment, the strobe samples 50 ns longer.
EVENT LOG
Display Log
The event log provides a history of printer errors. It contains the 12 most recent errors that have occurred on the
printer. The most recent error displays in position 1 and the oldest error displays in position 12 (if 12 errors have
occurred). If an error occurs after the log is full, the oldest error is discarded. Identical errors in consecutive
positions in the log are entered, so there may be repetitions. All 2xx and 9xx error messages are stored in the
event log.
Print Log
Additional diagnostic information is available when you print the event log from DIAGNOSTICS rather than
CONFIG MENU.
The printed event log can be faxed to Lexmark or your next level of support for verification or diagnosis.
Clear Log
Use Clear Log to remove the current information in the Event Log. This affects both the viewed log and the
printed log information.

Use Print Tests to locate a problem with media feed or with media transportation along the media path.
Due to the method used to generate Print Tests, grid lines may display a noticeable amount of jitter or
unevenness. This is normal for Print Tests.
Transport motor
The rotating force of the transport motor is transmitted through the gear and the pulley (25 tooth) to components
that need mechanical driving force as shown in the following diagram.
The driving force transmitted to the gear drives the transport roll assembly, multipurpose feeder (MPF) feed roll,
registration roll assembly, fuser assembly, and exit 1 media exit roll assembly through the clutch and gears.
The driving force transmitted to the pulley (25 tooth) drives the exit 1 media exit roll assembly through the gears.
The driving force transmitted to the fuser assembly drives the heat roll.
PC cartridge motor
The rotating force of the PC cartridge motor is transmitted through the gears to components that need a
mechanical driving force as shown in the following diagram.
PC cartridge motor
Transfer roll
The driving force transmitted to the PC cartridge drives the drum. The driving force is then transmitted to the
transfer roll assembly by direct contact with the drum.
Media transport
Media is supplied from the MPF, tray 1 or tray 2, and is transported to the printer along the media transport path
shown below.
MPF Tray 1 Tray 2
Feed roll
Drum
PC cartridge
Heat roll
Pressure roll
The following is a cross section of the laser printer, showing main components directly associated with the media
path and transport.
It is necessary to adjust the front media tray guide assembly, rear media tray guide and media tray end guide of
the media tray assembly to match the media size.
The front media tray guide assembly can be adjusted to different media sizes by moving the guides to the front
or rear. These guides come into contact with the media and hold it in position.
The rear media tray guide moves together with the front media tray guide assembly.
The media tray assembly is designed so it can adapt to the media length in the media feed direction by moving
the media tray end guide to the left or right.
Bottom plate
The force pushing up the bottom plate is transmitted by the driving force of the motor on the media feed unit
assembly to the lift up shaft through the gear (13/60 tooth) and sector gear (12 tooth). The bottom plate is
pushed up by the rotation of the lift up shaft, which causes the supplied media to come in contact with the pick
roll.
Bottom plate
Front media tray guide assembly
The media size set for the media tray assembly is transmitted to the switch (media size) by moving these guides.
The media size is detected by the on/off information of these switches.
Since tray 1 and tray 2 are functionally equivalent in terms of the switch (media size), sensor (media out),
sensor (media level) and sensor (pre-feed), only the components of one tray are described here.
The media feed unit assembly is a mechanical unit supplying media from the media tray assembly to the printer.
The driving force, from the media feed lift motor on the media feed unit assembly, is transmitted to the three
media feed rolls to feed media.
When the pick roll picks up media, the remaining media decreases, and the actuator of the
sensor (media level) lowers accordingly. When the sensor (media level) detects the lowering, the media feed lift
motor is activated to lift the lift up shaft and the bottom plate accordingly. Thus, the remaining media is ready to
be fed.
This motor is activated to feed media and to lift the bottom plate. When feeding media, it rotates forward to drive
the pick roll. When lifting the bottom plate, it rotates reversely to drive the tray module gears to lift the lift up shaft.
This switch (media size) sets the size of media supplied from each media tray assembly. A signal indicating the
media size is transmitted as a voltage to the printer engine card assembly.
If media runs out in a media tray assembly, the actuator lowers and the actuator flag, unlocks the sensing area of
the sensor (media out). The sensor light is transmitted. When the sensing area is blocked (media is present), the
signal is off.
This sensor detects by the actuator position whether media in the media tray assembly is lifted. When the flag of
the actuator unblocks the sensing area of the sensor (media level), the sensor detects that the media has been
lifted.
Sensor (pre-feed)
This sensor detects a media jam in the media tray assembly by the media position and sensor on/off time.
The sensor on/off states can be monitored by media passing through the sensor (pre-feed) sensing area.

The MPF is a mechanical unit suppling media to the printer. The driving force from the transport motor of the
dual drive motor assembly is transmitted to the MPF feed roll to feed media.
The MPF feed solenoid transmits the driving force from the main motor to the MPF feed roll.
The sensor (MPF media in) detects whether media is present on the MPF.
The MPF side guides detects the width (length in the main scanning direction) of media on the MPF.
MPF media transport roll ASM
Sensor (MPF media out)
The size of media on the MPF is transmitted by moving the MPF side guide, and is determined by the printer
engine card assembly.
The transfer roll assembly is driven by direct contact with the drum of the PC cartridge.
The transfer roll assembly applies positive charges to the rear surface of the media when the media passes
between the transfer roll assembly and the drum. The negatively charged toner image is attracted by positive
charges on the rear surface of the media. Thus, the toner image is transferred from the drum surface to the
media surface.
PC cartridge
Printhead assembly
The printhead scans the drum surface with a laser beam. It consists of four components: laser diode (LD) card
assembly, printhead motor, polygon mirror, and start of scan card assembly.
1. LD card assembly generates a laser beam with the two LDs of LD1 and LD2. The beam is turned on or
off according to a print data signal.
2. Printhead motor/polygon mirror the polygon mirror is mounted to the shaft of the printhead motor, and is
rotated at a high speed by the printhead motor. The mirror rotation shifts the incidence and reflection
angles of a laser beam to scan the laser beam in the drum axial direction. The laser beam reaches the
polygon mirror as it passes through the lens (L1), lens (L2), and window. The laser beam then arrives at
the drum surface.
3. SOS card assembly when a laser beam hits the SOS sensor on the SOS card assembly, the beam is
converted to an electrical signal (SOS signal), and detects the initial position where a scan starts on each
line.
When a laser beam is scanned across the drum surface from one end to the other while turning on and off the
beam, one line of latent image is created. If the scanning by the laser beam is repeated while rotating the drum,
a two-dimensional image is created. The resolution in the scanning direction (from right to left) is determined by
the rotational speed of the printhead motor, depending on how quickly the laser is adjusted. The resolution in the
process direction (from top to bottom) is determined by the rotational speed of the printhead motor. (The higher
the scanning speed becomes, the sooner the scanning of the next row can be started.)

Fuser
Heat roll
The heat roll is a hollow metal tube with a coated surface. This tube is heated by the inner heater rod. The heat
is applied to the media passing between the heat roll and pressure roll, fusing the toner on the media.
Pressure roll
The pressure roll is a metal shaft coated with sponge rubber. Pressure is applied to the media between the
pressure roll and heat roll, pressing the melted toner against the media.
Heater lamp
The heater rod of the lamp is compressed of a quartz glass tube containing a heater coil. A terminal is mounted
to the end of the heater rod via a harness. Three heater lamps are provided: the main heater rod to heat entire
heat roll, and the sub heater lamp 1 and 2 to heat the central portion of the heat roll.
Thermostat
If the heat roll temperature exceeds the preset temperature, the thermostat cuts off the circuits of the main
heater rod and sub heater rods 1 and 2.
Center thermistor
The center thermistor monitors the surface temperature of the media-feed portion of the heat roll to control on/off
of the main heater rod and sub heater rods 1 and 2.
Rear thermistor
The rear thermistor monitors the surface temperature at the rear side of the heat roll to switch the heater rod to
use.
The pressure roll thermistor monitors the temperature of the pressure roll to control the idling time for fuser
warm-up before printing.
The fuser exit sensor detects the arrival of media at the detection point in the exit area of the fuser, and also
detects the ejection of media from this point.

Exit
Exit 1 ejects printed media from the printer to the standard bin 1. With the optional exit 2 installed, it is also
possible to eject media to the standard bin 2 by changing the orientation of the diverter gate on the exit 1.
Drives the exit 1 media exit roll assembly that feeds media to each bin. With the optional duplex installed, this
motor also functions to reversely feed media to the duplex.
The exit 1 media exit roll assembly feeds printed media from the fuser to the standard bins.
The sensor (standard bin 1 full) detects whether the exit 1 face down tray is full by moving the actuator up and
down.
The media diverter gate switches the media transport path. When the media diverter gate is lifted, media is fed
to the standard bin exit 1. When it is lowered, media is fed to the standard bin exit 2.

Finisher AC output
Supplies power to the finisher from the main LVPS (low voltage power supply) card assembly.
Switch (printer front door interlock) and switch (printer left door interlock)
The switch is a safety switch to cut off a 24 VDC power supply from the LVPS card assembly to the high volt
power supply (HVPS) card assembly, printer engine card assembly and to the dual motor assembly, while the
printer front door assembly and the printer left door assembly are open.
The switch (PC interlock) 5 V interlock is a safety switch to cut off a 5 VDC power supply from the LVPS card
assembly to the printhead while the PC cartridge is removed.
The switch (left lower door interlock) detects open or close of the printer left lower door assembly.
The fuser cooling fan discharges air from the printer to prevent excessive temperature increase.
The LVPS card assembly generates low voltages (5 V and 3.3 V for logic circuits, 5 V for laser diodes, and 24 V
for motors/clutches) from AC power. It also contains the fuser relay to feed/cut off AC power to the heater rod of
the fuser assembly.
The HVPS card assembly generates AC power, a high DC voltage, and feeds them to the charge roll,
development (magnet roll), transfer roll assembly.
The printer engine card assembly controls printing operation based on the communication with the RIP card
assembly and on sensor/switch information. It also controls optional module boards.
The RIP card assembly connected to the printer engine card assembly controls the entire system.
The transport roll assembly feeds media from tray 2 or an optional tray to the registration roll assembly.
The registration roll assembly feeds media from all trays to the PC cartridge or fuser.

Printhead control
The on/off control of the printhead motor is performed according to the mode of operation as shown below.
The printhead goes into ready state after the specified period passes since the reception of the printhead MPA
start signal and the SOS cycle exceeds the reference value.
Fuser control
The on/off control of the main/sub heater lamps is performed based on the fuser control temperature. The fuser
transmits between the five states (warm up, ready, standby, print, and low power) depending on the heat roll
surface temperature or printer conditions.
The fuser temperature control starts when the fuser ready in the LVPS card assembly is turned on after a preset
time period has passed from power on. If a failure occurs, the heater lamps are turned off, the fuser ready is
turned off, and then the fuser temperature control is stopped.
The center and rear thermistors detect the heat roll surface temperature (fuser temperature) to regulate the
temperature at the target control temperature by turning on or off the main/sub heater lamps.
Fuser warm-up
The fuser warm-up starts at the time of power on, interlock open or close, jam reset, or return from the low power
mode, and ends when the ready temperature is attained, when a failure occurs, or when executing diagnosis.

Exposure
The Printhead generates a beam of laser light. Image data received from the RIP card assembly modulates this
beam, turning it on and off according to image information that is received from the host computer and software.
Through the use of a series of rotating and stationary mirrors within the Printhead, the beam scans the negative
charged drum surface. Whenever the print controller sends a command to print a black pixel, the laser switches
on long enough to shine onto the drum at a single pixel point. That point is now discharged and slightly less
negative than the surrounding negative charge. The less negative areas are considered positive. This discharge/
no discharge process creates an invisible, electrostatic image on the surface of the drum. This image is called a
latent image.
The Printhead also helps to clean and prepare the drum by scanning the surface of the drum at the beginning of
each individual printer cycle. This action discharges a residual DC charge that may still remain on the Drum from
the last print cycle.
Development
The toner contained within the PC Cartridge has a magnetic property that causes it to adhere to the Magnetic
Roll. The Metering Blade spreads the toner into a very thin layer on the Magnetic Roll. Friction between the
Magnetic Roll and the CM Blade generates a small electrical charge that is transferred to the toner.
The surface of the Magnetic Roll is made up of a thin sheet of conductive material. The HVPS supplies the
Magnetic Roll with two voltages; a DC voltage and an AC voltage. The DC voltage is used to transfer toner from
the Magnetic Roll to the surface of the drum. The AC voltage agitates the toner on the Magnetic Roll, making
toner transfer easier.
The Magnetic Roll maintains a negative DC electrical potential. Negative charged areas of the drum have a
lower electrical potential, or higher relative negative value than the Magnetic Roll. Discharged areas of the drum
have a higher electrical potential, or lower relative negative value, than the Magnetic Roll. A discharged point on
the surface of the drum now appears less negative in relation to the negative charge on the Magnetic Roll.
The toner adhering to the Magnet Roll is always in contact with the drum surface. When a less negative point on
the drum (a discharged area) comes in contact with the more negative charged toner on the Magnet Roll, toner
transfers from the Magnet Roll to that point on the drum. There is now a visible toner image on the drum surface.
The image is called a developed image.

Transfer
As the paper travels between the Transfer Roll and the drum surface, the Transfer Roll applies a positive charge
to the back of the printing paper. This positive charge transfers the negative charged toner image from the drum
surface to the top surface of the paper. The toner image is now on the paper and the paper is now stuck to the
drum surface due to the relative electrical differences between the negative electrical charge of the inner
conductive layer of the drum and the positive electrical charge of the paper.
Cleaning
The Cleaning Blade removes any toner that remains on the drum after the transfer process. The toner that the
Cleaning Blade removes is collected inside the sealed PC Cartridge and reused.
Discharge
At both the start and the end of each individual printer cycle, the HVPS supplies the charge roll with an AC
voltage that is used to electrically clean the drum. The AC voltage removes any residual DC charge that was left
from the previous print cycle.
At the beginning of each individual printer cycle, the Printhead scans the surface of the drum, further discharging
any residual DC charge that may be left on the drum.

4. Repair information
Keep the ESD-sensitive part in its original shipping container (a special ESD bag) until you are ready to
install the part into the machine.
Make the least-possible movements with your body to prevent an increase of static electricity from clothing
fibers, carpets, and furniture.
Put the ESD wrist strap on your wrist. Connect the wrist band to the system ground point. This discharges
any static electricity in your body to the machine.
Hold the ESD-sensitive part by its edge connector shroud (cover); do not touch its pins. If you are removing
a pluggable module, use the correct tool.
Do not place the ESD-sensitive part on the machine cover or on a metal table; if you need to put down the
ESD-sensitive part for any reason, first put it into its special bag.
Machine covers and metal tables are electrical grounds. They increase the risk of damage because they
make a discharge path from your body through the ESD-sensitive part. (Large metal objects can be
discharge paths without being grounded.)
Prevent ESD-sensitive parts from being accidentally touched by other personnel. Install machine covers
when you are not working on the machine, and do not put unprotected ESD-sensitive parts on a table.
If possible, keep all ESD-sensitive parts in a grounded metal cabinet (case).
Be extra careful in working with ESD-sensitive parts when cold-weather heating is used, because low
humidity increases static electricity.
Removal procedures
CAUTION: Remove the power cord from the printer or electrical outlet before connecting or
disconnecting any cable or electronic board or assembly for personal safety and to prevent damage
to the printer. Disconnect any connections between the printer and PCs/peripherals. The

This chapter describes procedures for printer preventive maintenance. Follow these recommendations to help
prevent problems and maintain optimum performance.
If any unsafe conditions exist, find out how serious the hazard could be and if you can continue before you
correct the hazard.
Damaged, missing, or altered parts, especially in the area of the on/off switch and the power supply
Damaged, missing, or altered covers, especially in the area of the top cover and the power supply cover
Possible safety exposure from any non-Lexmark attachments
MEDIA TRAYPRINTER
2TM/TTM (if equipped)
Lubrication specifications
Lubricate only when parts are replaced or as needed, not on a scheduled basis. Use of lubricants other than
those specified can cause premature failure. Some unauthorized lubricants may chemically attack
polycarbonate parts. Use IBM no. 10 oil, P/N 1280443 (Approved equivalents: Mobil DTE27, Shell Tellus 100,
Fuchs Renolin MR30), IBM no. 23 grease (Approved equivalent Shell Darina 1), and grease, P/N 99A0394 to
lubricate appropriate areas. Use Nyogel type 774 to lubricate the Fuser Drive Assembly and Nyogel 744 to
lubricate the ITU and Cartridge Drive assemblies.
Scheduled maintenance
The operator panel displays the message 80 scheduled maintenance at each 300K page count interval. It is
necessary to replace the fuser assembly, transfer roller, and feed, pick and separation rollers at this interval to
maintain the print quality and reliability of the printer. The parts are available as a maintenance kit with the
following part numbers:
After replacing the kit, the maintenance count must be reset to zero to clear the 80 scheduled maintenance
message.
When performing the 300K scheduled maintenance procedure, the following areas should be cleaned of
media dust and toner contamination:
Media trays
PC cartridge area
