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
cable 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 top cover without mounting the toner cartridge and the drum unit can
damage this product.
