SERVICE MANUAL
PREVENTION OF PHYSICAL INJURY
1. Before disassembling or assembling parts of the printer and peripherals, make sure that the printer power cord is unplugged.
2. The wall outlet should be near the printer and easily accessible.
3. If any adjustment or operation check has to be made with exterior covers off or open while the main switch is turned on, keep hands away from electrified or mechanically driven components.
4. The printer drives some of its components when it completes the warm-up period. Be careful to keep hands away from the mechanical and electrical components as the printer starts operation.
5. The inside and the metal parts of the fusing unit become extremely hot while the printer is operating. Be careful to avoid touching those components with your bare hands.
HEALTH SAFETY CONDITIONS
Toner and developer are non-toxic, but if you get either of them in your eyes by accident, it may cause temporary eye discomfort. Try to remove with eye drops or flush with water as first aid. If unsuccessful, get medical attention.
OBSERVANCE OF ELECTRICAL SAFETY STANDARDS
1. The printer and its peripherals must be serviced by a customer service representative who has completed the training course on those models.
2. The NVRAM module (option) installed on the controller has a lithium battery which can explode if replaced incorrectly. Replace the NVRAM only with an identical one. The manufacturer recommends replacing the entire NVRAM. Do not recharge or burn this battery. Used NVRAM must be handled in accordance with local regulations.
3. The optional fax and memory expansion units contain lithium batteries, which can explode if replaced incorrectly. Replace only with the same or an equivalent type recommended by the manufacturer. Do not recharge or burn the batteries. Used batteries must be handled in accordance with local regulations.
SAFETY AND ECOLOGICAL NOTES FOR DISPOSAL
1. Do not incinerate toner bottles or used toner. Toner dust may ignite suddenly when exposed to an open flame.
2. Dispose of used toner, the maintenance unit which includes developer or the organic photoconductor in accordance with local regulations. (These are non-toxic supplies.)
3. Dispose of replaced parts in accordance with local regulations.
4. When keeping used lithium batteries in order to dispose of them later, do not put more than 100 batteries per sealed box. Storing larger numbers or not sealing them apart may lead to chemical reactions and heat build-up.
5. Dispose of used fusing oil in accordance with local regulations.
LASER SAFETY
The Center for Devices and Radiological Health (CDRH) prohibits the repair of laser-based optical units in the field. The optical housing unit can only be repaired in a factory or at a location with the requisite equipment. The laser subsystem is replaceable in the field by a qualified Customer Engineer. The laser chassis is not repairable in the field. Customer engineers are therefore directed to return all chassis and laser subsystems to the factory or service depot when replacement of the optical subsystem is required.
!WARNING
Use of controls, or adjustment, or performance of procedures other than those specified in this manual may result in hazardous radiation exposure.
!WARNING
WARNING: Turn off the main switch before attempting any of the
procedures in the Laser Optics Housing Unit section. Laser beams can seriously damage your eyes.

1.5 NOTES FOR TRANSPORTING THE MACHINE

1.5.1 MACHINE STANDS

If it is difficult to slide the machine across the floor after installing the optional paper feed unit or LCT, remove the two stands with the following procedure.
[A]
G080I910.WMF
[B]
G080I911.WMF
1. Remove all trays in the optional paper feed unit or LCT.
2. Remove the front stand [A] (! x 2).
3. Remove the rear stand [B] (! x 2, 2 brackets).
CAUTION: Reinstall the two stands in their original positions, or the machine might
tip over when drawing out the paper trays and so on.
1-10
17 January, 2003 NOTES FOR TRANSPORTING THE MACHINE

1.5.2 MACHINE BODY

!CAUTION
Fix the transfer belt in its position before moving the machine, otherwise the transfer belt and the black PCU may be damaged.
Before transporting the machine for both short and long hauls, return it to its original condition.
1. Remove the toner cartridges to prevent toner from flowing into the toner supply tube due to vibrations experienced during transport. This may cause the tube to be clogged with toner.
2. Put air packing into the toner cartridge holder to shield the toner supply entrance. This prevents toner from flowing out to the toner cartridge holder.
3. Set the lock pin (which comes with the machine) in the transfer belt unit.
NOTE: The lower end of the transfer belt moves. The surfaces of the belt and
PCU may be damaged by the friction between them if you transport the machine without locking the belt.
Installation
4. Make sure there is no paper left in the paper trays and fix down the bottom plates with a sheet of paper and tape.
5. Empty out the waste toner bottle and attach securing tape to prevent the bottle from coming out.
6. Empty out the waste oil bottle and attach securing tape to prevent the bottle from coming out.
[A]
G080I904.WMF
7. Turn the release lever [A] counterclockwise to its lowermost position. (The lever does not stay in this position if you do not hold it.) Stick the lever in this position with tape. NOTE: The release lever lifts the transfer belt up and presses it against the
black PCU. The surfaces of the belt and PCU may be damaged by the friction between them if you transport the machine with the two units in this position.
1-11
NOTES FOR TRANSPORTING THE MACHINE 17 January, 2003
8. Attach shipping tape to the covers and doors, or shrink-wrap the machine tightly.
NOTE: 1) If pre-installing machines for some test prints at a service depot, use a
jig oil supply unit, and not the oil supply unit enclosed as an accessory.
This is because the toner supply system uses a touch-and-release mechanism, which can cause the unit to move freely up and down during transport if shipping the mainframe with the oil supply unit installed. This in turn may cause damage to the white holder on the fusing unit. However if simply moving the machine from floor to floor, the oil supply unit can be left installed.
2) If shipping a used machine to a new location, dispose of the used oil supply unit and install a new one because of the reason explained above. This is not necessary when simply moving the machine from floor to floor.
3) Whenever having moved the machine to a new location, be sure to perform Auto Adjust (User Program mode) or forced Line Position Adjustment (SP5-993-002) to optimize color line alignment.
4) Make sure that the side fences in the trays are properly positioned to prevent color shifting.

Adjustment Procedure
1. Enter SP mode and access SP5-997.
2. Print out the pattern (14: 1-dot trimming pattern) with SP5-997. NOTE: Registration may change slightly print by print as shown above.
Therefore print a few pages of the trimming pattern for step 3 and 4, and average the leading edge and side-to-side registration values and adjust each SP mode.
3. Perform the leading edge registration adjustment.
1) Check the leading edge registration and adjust it with SP1-001.
2) Select the adjustment conditions (paper type and process line speed).
3) Input the value then press the [Escape] key.
4) Check the leading edge adjustment by generating the trim pattern.
4. Perform the side to side registration adjustment.
1) Check the side to side registration and adjust it with SP1-002.
2) Select the adjustment conditions (paper feed station).
3) Input the value then press the [Escape] key.
4) Check the side to side adjustment by generating the trim pattern.

3.2.2 COLOR REGISTRATION

Line Position Adjustment
Normally, the automatic line position adjustment is executed under a specified condition to optimize the color prints. If color registration shifts, execute “Auto Adjust” with the user tools (Maintenance menu – Color registration) or SP5-993-2 to do the forced line position adjustment. In addition, it is recommended to perform the line position adjustment under the following conditions:
After transporting or moving the printer (If printers are pre-installed at the
workshop and transported to the user location, forced line position adjustment should be done after printer installation is completed at the user location.)
When opening the drum positioning plate
When removing or replacing the motors, clutches, and/or gears related to the
drum/development/transfer sections
When removing or replacing the transfer belt or laser optical housing unit
Adjustment of Line Speed for Thick Paper
You must adjust the line speed of the fusing unit (the speed of development motor­K) under the following conditions:
The color registration shifts more on the trailing edge than on the leading
edge.
This problem has not been solved by the line position adjustment.
Use the following user tool for this adjustment:

3.2.3 PRINTER GAMMA

NOTE: Normally, the printer gamma is enough to adjust the color balance to
achieve the optimum print output. The gamma correction is only required
Adjustment Overview
Make the gradation scales on the printout smooth from the highlight to the shadow density. Adjust the CMY gradation scale at the top of the chart by balancing the density of the C, M, and Y gradation scales – the CMY gray scale should change smoothly from minimum to maximum, and there should be no coloration.
For each color, you can adjust 15 points between 0 (lowest density) and 255 (highest density).
The gradation scales marked “Default Value” are printed according to the default gamma settings. The gamma adjustment changes the densities at the adjustable points in the gradation scale. The gradation scale marked “Current Value” shows the current settings.
During the adjustment procedure, compare the “Current Value” gradation scale with the “Default Value” Select the density for each of the 15 adjustable points, excluding points 0 and 255, from the “Default Value” gradation scale.
for fine-tuning to meet the user requirements.
The NVRAM holds three printer gamma settings, those saved this time (Current), those saved in the preceding adjustment (Previous), and the factory settings (Factory).
Adjustment Procedure
1. Enter SP mode.
2. Select “1. Service”
3. Select “Data Recall” and load the settings that will serve as the base for the adjustment.
4. Select “Mode Selection”, and select the print mode that you are going to adjust.
5. To review the image quality for these settings, choose “Test Page” to print out a color calibration test sheet.
6. Select “Gamma Adj.”
7. Adjust the color density at each of the 15 points for a color (CMY and K).
8. When the density setting is complete for all colors, print out a color calibration test sheet again and make sure that the gradation scale for each printed color is smooth and that the CMY gradation scale is gray. Repeat the adjustment if there is an anomaly.
9. If the adjustment results prove satisfactory, execute “Data Save.”
