SERVICE MANUAL

!IMPORTANT SAFETY NOTICES

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.

MACHINE INSTALLATION 17 January, 2003

1.4 MACHINE INSTALLATION

Refer to the Operating Instructions. If the customer has made a service contract, change the settings of the following SP mode menus in accordance with it.

NOTE: 1) The meter charge mode must be enabled for any meter click counter

contract (☛ SP5-930-1).

2) One of the counter methods (developments/prints) must be selected in accordance with the contract (☛ SP5-045-1).

3) The default of the meter-charge mode is "off."

4) The meter-charge counter cannot be reset.

Item SP No. Function Default

Meter charge

Counting method

A3/11" x 17" double counting

SP5-930-1 Specifies whether the meter charge mode is

enabled or disabled.

Meter charge mode enabled:

• The Counter menu appears immediately

after the Menu key is pressed.

• The counter type selected by the counting

method (SP5-045-1) can be displayed with the Counter menu.

• The counter values can also be printed with

the Counter menu.

• The selected counter starts from a negative

number.

• When the ACS mode is on, a monochrome

page is counted as such even if it follows a color page.

Meter charge mode disabled:

• The Counter menu is not displayed.

• The total counter starts from 0.

• When the ACS mode is on, a monochrome

page is counted as a color page if it follows a color page.

NOTE: The menu items, "Show Counter" and

"Print," appear in the UP mode after the meter charge mode (SP5-930-1) is enabled or the optional CF expander is installed. (These menu items always appear after the CF expander is installed.)

SP5-045-1 Specifies whether the counting method used

in meter charge mode is based on developments or prints.

Important:

This SP can only be done before the negative counters are reset with SP7-825-001.

SP5-104-1 Specifies whether the counter is doubled for

A3/11" x 17" paper.

"OFF"

"0": Developments

"No": Single counting

NOTES FOR TRANSPORTING THE MACHINE 17 January, 2003

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.
