Clean the scanner glass
NOTE: 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.
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.
