1. Be sure that the power cord is unplugged before disassembling or
assembling parts of the copier or peripherals.
2. The wall outlet should be near the copier and easily accessible.
3. Note that electrical voltage is supplied to some components of the copier
and the paper tray unit even while the main power switch is off.
4. If you start a job before the copier completes the warm-up or initializing
period, keep hands away from the mechanical and electrical components
until job execution has started. The copier will start making copies as soon
as warm-up or initialization is finished.
5. The inside and the metal parts of the fusing unit become extremely hot while
the copier is operating. Be careful to avoid touching those components with
your bare hands.
HEALTH SAFETY CONDITIONS
Toner and developer are nontoxic, but getting either of these into your eyes may
cause temporary eye discomfort. Try to remove with eye drops or flush with
water. If material remains in eye or if discomfort continues, get medical attention.
OBSERVANCE OF ELECTRICAL SAFETY STANDARDS
The copier and its peripherals must be installed and maintained by a customer
service representative who has completed the training course on those relevant
models.
LITHIUM BATTERIES
Incorrect replacement of lithium battery(s) on the FCU may pose risk of
explosion. Replace only with the same type or with an equivalent type
recommended by the manufacturer. Discard used batteries in accordance with
the manufacturer’s instructi ons.
SAFE AND ECOLOGICAL DISPOSAL
1. Do not incinerate toner bottles or used toner. Toner dust may ignite suddenly
if exposed to an open flame.
2. Dispose of used toner, developer, and organic photoconductors in
accordance with local regulations. (These are nontoxic supplies.)
3. Dispose of replaced parts 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 not specified in this manual, or performance of
adjustments or procedures not specified in this manual, may result in
hazardous radiation exposure.
!
WARNING FOR LASER UNIT
WARNING: Turn off the main switch before atte mpting any of the

3. REPLACEMENT AND AD JUSTMENT
3.1 PRECAUTIONS
3.1.1 GENERAL
!
CAUTION
Turn off the main power switch and unplug the machine before starting any
of the replacement procedures described in this section.
But note that you should not turn off the main switch while mechanical parts are
active, as this may cause parts to stop out of home position. Attempting to remove
or install the PCU or other such units while parts are out of home position may
result in damage. Wait for operation to stop before turning off the machine.
3.1.2 LITHIUM BATTERIES
!
CAUTION: Lithium Batteries
Incorrect replacement of lithium battery(s) on the FCU poses risk of
explosion. Replace only with the same type or with an equivalent type
recommended by the manufacturer. Discard used batteries in accordance
with the manufacturer’s instructions.
Adjustment
Replacement
3.1.3 PCU (PHOTOCONDUCTOR UNIT)
The PCU consists of the OPC drum, charge roller, development unit, and cleaning
components. Observe the following precautions when handling the PCU.
1. Never touch the drum surface with bare hands. If the drum surface is dirty or if
you have accidentally touched it, wipe it with a dry cloth, or clean it with wet
cotton and then wipe it dry with a cloth.
2. Never use alcohol to clea n the drum. Alcohol will dissolve the drum surfac e.
3. Store the PCU in a cool dry place.
4. Do not expose the drum to corrosive gases (ammonia, etc.).
5. Do not shake a used PCU, as this may cause toner and developer to spill out.
6. Dispose of used PCU components in accordance with local regulations.
3.1.4 TRANSFER ROLLER
1. Never touch the surface of the transfer roller with bare hands.
2. Be careful not to scratch the transfer roller, as the surface is easily damaged.
3-1
Page 37
PRECAUTIONS24 July, 2001
3.1.5 SCANNER UNIT
1. Use alcohol or glass cleaner to clean the exposure and scanning glass. This
will reduce the static charge on the glass.
2. Use a blower brush or a water-moistened cotton pad to clean the mirrors and
lenses.
3. Take care not to bend or crease the exposure lamp’s ribbon cable.
4. Do not disassemble the lens unit. Doing so will throw the lens and copy image
out of focus.
5. Do not turn any of the CCD positionin g screws. Doing so will throw the CCD out
of position.
3.1.6 LASER UNIT
1. Do not loosen or adjust the screws securing the LD drive board on the LD unit.
Doing so will throw the LD unit out of ad justment.
2. Do not adjust the variable resistors on the LD unit, as these are permanently
adjusted at the factory. If replacement of the LD drive board is necessary,
replace the entire LD unit.
3. Keep the polygon mirror and toroidal lens free of dust. Laser performance is
very sensitive to dust on these components.
4. Do not touch the shield glass, the lenses, or the surface of the polygon mirror
with bare hands.

1. After installing the fusing thermistor, make sure that it is in contac t with the hot
roller and that the roller can rotate freely.
2. Be careful to avoid damage to the hot roller stripper pawls and their tension
springs.
3. Do not touch the fusing lamp and rollers with bare hands.
4. Make sure that the fusing lamp is positioned correctly and that it does not touch
the inner surface of the hot roller.

1) If a problem involves circuit boards: Before deciding to replace a circuit
board, first see if you can solve the problem by disconnecting and then
reconnecting all connectors.
2) If a problem involves a motor lock: Check the mechanical load first,
before deciding whether to replace motors or sensors.
3) If working on a fax-equipped machine, keep in mind that switching

DUMPING THE FUSER TEMPERATURE LOG24 July, 2001
4.4 DUMPING THE FUSER TEMPERATURE LOG
The FCU monitors the fuser temperature and maintains a log of the most recent
temperature values. If a heating-related SC error occurs (error code "9-22"; SCs
541 to 552), you may wish to print out a dump of the logged data before clearing
the SC condition. The printout can then be submitted for analysis.
To dump the log, proceed as follows.
1. Before clearing the SC, use SP7-955 to write "02h" into address 40191C. This
freezes the log data.
2. Clear the SC.
3. Use SP-992 setting "3" (☛ 5.1.5) to print out a dump of addresses 401900 to
410CFF.
4. Use SP7-955 to write "00h" into 40191C. This will restart temperature logging.
