Cleaning Your Machine
To maintain the print quality, follow the cleaning procedures below each
time the toner cartridge is replaced or if print quality problems occur.
NOTE
: While cleaning the inside of the machine, be careful not to touch the
transfer roller, located underneath the toner cartridge. Oil from your fingers can
cause print quality problems.
CAUTIONS
: Cleaning the cabinet of the machine with surfactants containing
large amounts of alcohol, solvent or other strong substances can discolor or
crack the cabinet.
Cleaning the Outside
Clean the cabinet of the machine with a soft lint-free cloth. You can dampen
the cloth slightly with water, but be careful not to be let any water drip onto
the machine or inside of it.

inside the machine. This buildup can cause print quality problems, such as
toner specks or smearing. Cleaning the inside of the machine clears or
reduces these problems.

Turn the machine off and unplug the power cord. Wait for the machine
to cool down.

down.
