Safety Notices
Important Safety Notices
Prevention of Physical Injury
1. Before disassembling or assembling parts of the machine and peripherals, make sure that the
machine power cord is unplugged.
2. The wall outlet should be near the machine and easily accessible.
If any adjustment or operation check has to be made with exterior covers off or open while the
3.
main switch is turned on, keep hands away from electrified or mechanically driven components.
4. The machine 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 machine starts operation.
5. The inside and the metal parts of the fusing unit become extremely hot while the machine is
operating. Be careful to avoid touching those components with your bare hands.
Health Safety Conditions
Toner is 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 machine and its peripherals must be serviced 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, the maintenance unit which includes developer or the organic
photoconductor in accordance with local regulations. (These are non-toxic supplies.)
Dispose of replaced parts in accordance with local regulations.
3.
• To prevent a fire or explosion, keep the machine away from flammable liquids, gases, and
aerosols. A fire or an explosion might occur.
1
• The Controller board on the MF model contains a lithium battery. The danger of explosion exists if
a battery of this type is incorrectly replaced. Replace only with the same or an equivalent type
recommended by the manufacturer. Discard batteries in accordance with the manufacturer's
instructions and 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.
• 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.

4. Replacement and Adjustment
Before You Start
General Precautions
• If there are printer jobs in the machine, print out all jobs in the printer buffer.
• Turn off the main power switch and unplug the machine before you do the procedures in this
section.
Use extreme caution when removing and replacing components. The cables in the machine are located
very close to moving parts; proper routing is a must.
After components have been removed, any cables that have been displaced during the procedure must
be restored as close as possible to their original positions. Before removing any component from the
machine, note any cable routings that may be affected.
Before servicing the machine:
1. Verify that documents are not stored in memory.
2. Remove the print cartridge before you remove parts.
3. Unplug the power cord.
4. Work on a flat and clean surface.
5. Replace with authorized components only.
6. Do not force plastic material components.
Make sure all components are returned to their original positions.
AIO
The AIO consists of the OPC drum, charge roller, development unit, cleaning components and toner
tank. Observe the following precautions when handling the AIO.
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 AIO in a cool dry place.
4. Do not expose the drum to corrosive gases (ammonia, etc.).
5. Do not shake a used AIO, as this may cause toner to spill out.
27
4. Replacement and Adjustment
6. Dispose of used AIO components in accordance with local regulations.
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 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.
Keep the polygon mirror and toroidal lens free of dust. Laser performance is very sensitive to dust
3.
on these components.
4. Do not touch the shield glass or the surface of the polygon mirror with bare hands.
5. Do not adjust the Laser Synchronization detector on the LD unit, as these are permanently adjusted
at the factory.
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.
Fusing
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.
Do not touch the fusing lamp and rollers with bare hands.
3.
4. Make sure that the fusing lamp is positioned correctly and that it does not touch the inner surface of
the hot roller.
Paper Feed
1. Do not touch the surface of 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 loaded paper size.
Scanner Unit (for M203/M204)
1. Clean the parts indicated by arrows with a soft damp cloth and then wipe the same parts with a dry
cloth to remove any remaining moisture.
