General Cautions
PCU (Photoconductor Unit)
The PCU consists of the OPC drum, development unit, charge roller, and cleaning unit. Follow the
cautions below when handling a PCU.
• Never touch the drum surface with bare hands. When the drum surface is touched or becomes
dirty, wipe it with a dry cloth or clean it with wet cotton. Wipe with a dry cloth after cleaning with
the cotton.
• Never use alcohol to clean the drum; alcohol dissolves the drum surface.
•
Store the PCU in a cool, dry place away from heat.
• Never expose the drum to corrosive gases such as ammonia gas.
• Never shake the used PCU. Doing so may cause toner and/or developer to spill out.
• Dispose of used PCUs in accordance with local regulations.
• Turn off the main power switch and disconnect the power cord before you start any of the
procedures in this section. To prevent toner leakage, never loosen or remove the screws shown in
the illustration below.
Transfer Roller Unit
• Never touch the transfer roller surface with bare hands.
•
Take care not to scratch the transfer roller as the surface is easily damaged.
