PCU and Quenching Lamp
When handling the photo conductor unit (PCU), use caution:
• Do not touch the OPC drum with your bare hands. When the OPC drum is unclean, clean it with dry
cloth, or clean it with wet cotton and wipe it with dry cloth.
• Do not use alcohol or any other chemicals to clean the OPC drum. These substances damage the
OPC-drum surface.
• Keep PCUs in a cool, dry place.
• Do not expose the OPC to any corrosive gas such as ammonia.
• Do not shake a used PCU. Remaining toner and developer may spill out.
• Dispose of used PCUs in accordance with local regulations.
