IMPORTANT SAFETY NOTICES
PREVENTION OF PHYSICAL INJURY
1. Before disassembling or assembling parts of the copier and peripherals,
make sure that the power cord is unplugged.
2. The wall outlet should be near the copier and easily accessible.
3. Note that some components of the copier and the paper tray unit are
supplied with electrical voltage even if the main power switch is turned off.
4. If a job has started before the copier completes the warm-up or initializing
period, keep hands away from the mechanical and electrical components
because the starts making copies as soon as the warm-up period is
completed.
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 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
The copier and its peripherals must be installed and maintained by a customer
service representative who has completed the training course on those models.
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, developer, and organic photoconductors in
accordance with local regulations. (These are non-toxic supplies.)
3. Dispose of replaced parts in accordance with local regulations.
Page 28
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 FOR LASER UNIT
WARNING: Turn off the main switch before attempting any of the
procedures in the Laser Unit section. Laser beams can
seriously damage your eyes.

GENERAL CAUTIONS
3. REPLACEMENT AND ADJUSTMENT
3.1 GENERAL CAUTIONS
Do not turn off the main switch while any of the electrical components are active.
Doing so may result in damage to units (such as the PCU) as they are pulled out or
replaced.
3.1.1 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 clean the drum. Alcohol will dissolve the drum surface.
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.
Adjustment
Replacement
3.1.2 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.
3.1.3 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.
SM 3-1 B039/B040/B043
Page 70
SPECIAL TOOLS AND LUBRICANTS
3.1.4 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. These are adjusted at the
factory.
3. The polygonal mirror and F-theta lens are very sensitive to dust.
4. Do not touch the toner shield glass or the surface of the polygonal mirror with
bare hands.
3.1.5 FUSING UNIT
1. After installing the fusing thermistor, make sure that it is in contact 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.
3.1.6 PAPER FEED
1. Do not touch the surface of the paper feed rollers.
2. To avoid misfeeds, the side and end fences in each paper tray must be
positioned correctly so as to align with the actual paper size.
3.1.7 IMPORTANT
1. After installing a new PCU, you must run SP2-214 to initialize the TD sensor.
After starting initialization, be sure to wait for it to reach completion (wait for the
motor to stop) before re-opening the front cover or turning off the main switch.
2. If the optional tray heater or optics anti-condensation heater is installed, keep
the copier's power cord plugged in even while the main switch is off, so that the
heater(s) remain energized.

3.4.6 CHANGING THE ORIGINAL SENSOR POSITIONS (8K/16K)
This procedure is for China models only. To enable detection of the following
original sizes, the original sensors must be moved from their factory-set positions
to the locations indicated in the drawing below right.
• 8K SEF (270 x 390 mm)
• 16K SEF (195 x 270 mm)
• 16K LEF (270 x 195 mm)
Once the sensors have been moved, they will detect paper sizes as follows.

B039R012.WMF
1. Set the machine to detect 8K/16K originals as follows.
• If the machine is equipped with the platen cover: Access SP mode 5-955-1,
and set the setting to 1 (=Yes). The machine will now detect 8K/16K rather
than B4/B5. (B4-SEF → 8K-SEF; B5-SEF → 16K-SEF; B5-LEF → 16K-LEF)
• If the machine is equipped with the ADF or ARDF: Access SP mode 5-955-2,
and set the setting to 1 (=Yes). The machine will now detect 8K/16K rather
than A3/A4/B4/B5. (A3-SEF/B4-SEF → 8K-SEF; B5-SEF/A4-SEF → 16KSEF; B5-LEF/A4-LEF → 16K-LEF)
• Note that making either of the above settings will disable use of SP mode 5-
911.
2. Turn off the power, and remove the exposure glass (☛ 3.4.1).
3. Remove APS sensors [A, B].
4. Remove screws [C, D] at the new mount positions.
5. Mount the original width sensor into the new position (from where you removed
screw [C]), and screw.
6. Mount the original length sensor into the new position (from where you
removed screw [D]), and screw it.
7. Screw screws back into their original holes.

adjust the alignment as follows.
2. Copy tray (☛ 3.3.3)
3. Loosen the four screws securing the laser unit (☛ 3.5.3).

at [C], and loosely screw it in at the center of the long hole [D].
NOTE: If you have already adjusted the alignment at least once, the screw will
already be in the long hole. If readjustment is necessary, just loosen
the screw and continue as follows.
5. Rotate the lever clockwise or counterclockwise. This allows you to shift the
corners of the pattern ±0.4 mm with respect to the leading and trailing edges of
the paper. Using trial and error, adjust until the trim pattern is even.
6. Tighten screw [A] at its new position.
