Clean the scanner glass
To clean the scanner glass
1. Turn off the device.
2. Lift the scanner lid.
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
CAUTION: 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.
