Routine maintenance C
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.
Use neutral detergents. Cleaning with
volatile liquids such as thinner or benzine
will damage the surface of the machine.
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. (For more information see
Important safety instructions on page 117.)
Be careful not to inhale toner.
