wipe the scanning glass, rollers and white backplate with a soft
cloth.

3. Cleaning the drum cartridge.
If you find that characters or parts of an image are missing from your
printed pages, the drum in the drum cartridge may need cleaning.
Follow the steps below to clean the drum.
1 Grasp the print compartment cover at both sides as shown, and
pull up to open the cover.
• Caution!
The fusing unit inside the print compartment becomes very hot during
operation. Do not touch the inside of the compartment or the paper
guide on the underside of the print compartment cover.
2 Grasp the finger hold on the toner cartridge handle where it is
marked PUSH, and pull the handle out. Hold the handle and pull
the toner cartridge out of the compartment.
• Place the toner cartridge on a sheet of paper on a level surface.
3 Grasp the tabs on the drum cartridge handle with both hands and
gently pull the cartridge out of the machine.
4 Take a sheet of clean paper and roll it into a tube. Roll it tightly
so that the diameter of the holes at each end is less than the
thickness of your little finger.
