Cleaning and Checking the machine
5
Clean the outside and inside of the machine regularly with a dry, lint-free cloth. When you replace the toner
cartridge or the drum unit, make sure that you clean the inside of the machine. If printed pages are stained
with toner, clean the inside of the machine with a dry, lint-free cloth.
WARNING
• DO NOT put a toner cartridge or a toner cartridge and drum unit assembly into a fire. It could explode,
resulting in injuries.
• DO NOT use flammable substances, any type of spray, or an organic solvent/liquid containing alcohol
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.
