3. Clean the glass by using a soft, lint-free cloth that has been sprayed with a mild
glass cleaner. Dry the glass with a dry, soft, lint-free cloth.
CAUTION: Use only glass cleaner to clean the scanner glass. Avoid cleaners
that contain abrasives, acetone, benzene, and carbon tetrachloride, all of which
can damage the scanner glass. Avoid isopropyl alcohol because it can leave
streaks on the glass.
CAUTION: Do not spray the glass cleaner directly on the glass. If too much
glass cleaner is applied, the cleaner could leak under the glass and damage
the scanner.
4. Close the scanner lid, and turn on the device.
Clean the exterior
NOTE: Before cleaning the device, turn off the power and unplug the power cord
from the electrical socket.
Use a soft, damp, lint-free cloth to wipe dust, smudges, and stains off of the case. The
exterior of the device does not require cleaning. Keep fluids away from the interior of
the device, as well as from the device control panel.
Clean the automatic document feeder
If the automatic document feeder picks up multiple pages or if it does not pick up plain
paper, you can clean the rollers and separator pad. Lift the automatic document feeder
cover to access the pick assembly inside the automatic document feeder, clean the
rollers or separator pad, and then close the cover.
