To clean the scanner glass
Turn off the device.
2. Lift the ADF.
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.


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.


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 ADF, and turn on the device.
