Routine Maintenance

CAUTION

We recommend that you put the drum unit and toner cartridge assembly on a piece of disposable paper or
cloth in case you accidentally spill or scatter toner.

To prevent damage to the printer from static electricity, DO NOT touch the electrodes shown in the
illustration.

Push down the green lock lever and take the toner cartridge out of the drum unit.

WARNING

DO NOT put a toner cartridge into a fire. It could explode, resulting in injuries.

Use neutral detergents.

DO NOT use cleaning materials that contain ammonia, alcohol, any type of spray, or any type of flammable
substance to clean the outside or inside of the machine. Doing this may cause a fire or electrical shock.
