Push down the green lock lever and take the toner cartridge out of the drum unit.
WARNING
• DO NOT put a toner cartridge or a toner cartridge and drum unit assembly into a fire. It could explode,
resulting in injuries.

or ammonia to clean the inside or outside of the machine. Doing so could cause a fire or electrical shock.
Instead, use only a dry, lint-free cloth.
