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.
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 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




8
photoconductor in accordance with local regulations. (These are non-toxic supplies.)
3. Dispose of replaced parts in accordance with local regulations.


To prevent a fire or explosion, keep the machine away from flammable liquids,
gases, and aerosols. A fire or an explosion might occur.


The Controller board on the DX-C200 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.

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.




5-1
[5]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.
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 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.
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.

Paper Feed

1. Do not touch the surface of paper feed rollers.
2. To avoid miss-feeds, the side and end fences in each paper tray must be positioned
correctly so as to align with loaded paper size.

Scanner Unit (for DX-C200)

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. Make sure to not bend or crease the exposure lamp's ribbon cable.



5-2
[5]Replacement and Adjustment

4. Do not disassemble the lens unit. This will cause the lens and copy image to get out of
focus.
5. Do not turn any of the LED positioning screws. This will put the LED out of position.

Releasing Plastic Latches




Many of the parts are held in place with plastic latches. The latches break easily, so release
them carefully. To release a latch, press the hook end of the latch away from the part to
which it is latched.

After Servicing the Machine
1. Make sure all parts that require grounding are properly grounded.
2. Make sure the interlock switch is functioning.
3. Do not leave unused solder or parts inside the machine.
4. Do not leave any tools inside the machine.
5. Make sure all wires are properly connected and routed.
6. Make sure wires are not jammed between parts of the machine.

Lithium Batteries (DX-C200)


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
