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
let any water drip onto or inside the machine.
Cleaning the Inside
During the printing process, paper, toner and dust particles can
accumulate 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.
1 Turn the machine off and unplug the power cord. Wait for
the machine to cool down.
2 Open the front cover and pull the toner cartridge out,
lightly pushing it down.
3 With a dry lint-free cloth, wipe away any dust and spilled
toner from the toner cartridge area and the toner cartridge
cavity.
C AUTION : To prevent damage to the toner cartridge, do not
expose it to light for more than a few minutes. Cover it with a
piece of paper, if necessary. Do not touch the black transfer roller
inside the machine.
