SAFETY PRECAUTIONS

To avoid creating secondary problems by mishandling, follow the warnings and precautions
below during maintenance work.

Caution:

- Be careful not to lose screws, washers, or other parts removed.

- Be sure to apply grease to the gears and applicable positions specified in this chapter.

- When using soldering irons or other heat-generating tools, take care not to accidentally

damage parts such as wires, PCBs and covers.

- Static electricity charged in your body may damage electronic parts. When transporting

PCBs, be sure to wrap them in conductive sheets.

- When replacing the PCB and all the other related parts, put on a grounding wrist band and

perform the job on a static mat. Also take care not to touch the conductor sections on the
flat cables or on the wire harness.

- After disconnecting flat cables, check that each cable is not damaged at its end or

shortcircuited.

- When connecting flat cables, do not insert them at an angle. After insertion, check that the

cables are not at an angle.

- When connecting or disconnecting cable connectors, hold the connector body, not the

cables. If the connector has a lock, release the connector lock first to release it.

- After a repair, check not only the repaired portion but also all connectors. Also check that

other related portions are functioning properly before operational checks.

- Violently closing the front cover without mounting the toner cartridge and the drum unit can

damage this main body.

- After an assembly, recommend the operation of "dielectric strength voltage check" and

"continuity check".

WARNING

Some parts inside the printer are extremely hot immediately after the printer is used. When
opening the front cover or back cover to access any parts inside the printer, never touch the
shaded parts shown in the following figures.
