IMPORTANT SAFETY NOTICES

PREVENTION OF PHYSICAL INJURY

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 instructions.

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 attempting any of the

procedures in the Laser Unit section. Laser beams can cause
serious damage to eyes.

PRECAUTIONS

3. REPLACEMENT AND ADJUSTMENT

3.1 PRECAUTIONS

3.1.1 GENERAL

CAUTION

Turn off the main power switch and unplug the machine before starting
replacement.

Before turning off the main power switch, check that no mechanical component is
operating. Mechanical components may stop out of their home positions if you turn
off the main power switch while they are operating. The component may be
damaged if you try to remove it when it is not in the home position.

3.1.2 LITHIUM BATTERIES

CAUTION: Lithium Batteries

Incorrect replacement of lithium battery(s) on the controller or on the fax
unit 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.

3.1.3 HALOGEN-FREE CABLE

CAUTION

Use extreme caution while handling cables.

To comply with local regulations, halogen-free cables are used in this machine.
Halogen-free cables are environment-friendly, but no stronger than conventional
cables. These cables may be damaged in any of the following cases:

• The cable is caught between hard objects such as brackets, screws, PCBs, and

exterior covers.

• The cable is rubbed on a hard object such as brackets, screws, PCBs, and

exterior covers.

• The cable is scratched with a hard object such as brackets, screws, PCBs,

exterior covers, screwdrivers, and fingernails.

Replacement

and

Adjustment

3.1.4 PCU (PHOTOCONDUCTOR UNIT)

The PCU consists of the OPC (Organic Photo Conductor) 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.

SM 3-1 B129 Series/B044 Series

PRECAUTIONS

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.

3.1.5 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.

3.1.6 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 positioning screws. Doing so will cause the CCD to
be misaligned.

3.1.7 LASER UNIT

1. Do not loosen or adjust the screws securing the LD drive board on the LD unit.
Doing so will cause the LD unit to be out of adjustment.

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.

3.1.8 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.

SPECIAL TOOLS AND LUBRICANTS

3.1.9 PAPER FEED

3. Specify "1."

4. Press the OK key.

5. Press the C key. The copy mode is activated.

6. Place an OHP sheet on the by-pass tray.

7. Press the C key. The copier feeds the OHP sheet, and reserve it between the
hot roller and the pressure roller about 20 seconds.

8. Wait until the OHP sheet is output.

9. Press the S key.

10. Make sure SP1-109-001 is selected.

11. Specify "0."

12. Press the OK key.

13. Quit the SP mode.

You should see an opaque stripe on the OHP sheet. This is the trace of the nip
band. The normal nip band is symmetrical to the OHP sheet. Both ends are slightly
thicker than the center.

NOTE 1: There are no specifications or standards for the nip band of this copier.
NOTE 2: If the band is not as described above, change the position of the spring

hooks (one on each side of the pressure roller). Then check the nip band again.
(The higher hook position produces greater tension.)
