To clean the scanner glass

1Disconnect the power cable from the scanner.

2Open the scanner lid.

3Clean the glass using a soft, lint-free cloth sprayed with a mild glass cleaner.

CAUTION Only use glass cleaner. Avoid 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.

4Dry the scanner glass with a dry, soft, lint-free cloth.

5When finished, reconnect the power cable to the scanner.

Fingerprints or smudges on the underside of the glass do not affect the appearance of scanned images because this area of the glass is outside the focal point of the scanner.
