Cleaning and checking 
the machine
A
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.
 
• 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.
(See Product Safety Guide: To use the 
product safely.)
 
 
Use neutral detergents. Cleaning with 
volatile liquids such as thinner or benzine 
will damage the surface of the machine.
