Clean the device
This section provides instructions for keeping the device in top working condition.
Perform these maintenance procedures as necessary.
Dust or dirt on the scanner glass, scanner lid backing, or scanner frame can slow
down performance, degrade the quality of scans, and affect the accuracy of special
features such as fitting copies to a certain page size.
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.
