ROUTINE MAINTENANCE 5 - 21
Cleaning
Clean the outside and inside of the printer regularly with a dry soft cloth. When you replace the toner
cartridge, make sure you clean the inside of the printer. If printed pages are stained with toner, clean the
inside of the printer with a dry soft cloth.
We recommend cleaning the following parts of the printer every 20,000 printed pages or every 12
months:
■Paper guides of the paper tray
■Registration roller
■Paper pick-up roller
■Transfer roller unit
■Transfer roller guide
■Exit roller
■OPC belt cartridge
■Charging roller
■Laser unit
■Dust proof glass
■Use water. Cleaning with volatile liquids such as thinner or benzine will damage the surface of
the printer.
■Do not use cleaning materials that contain ammonia. They could damage the printer, particularly
the toner cartridges.
