Clean the scanner glass
Clean the scanner glass under the following conditions:
• Streaks, scratches, or spots appear in images scanned from the scanner glass.
• After scanning a document that is dusty or dirty from the scanner glass.
• The environment is dusty.
To clean the scanner glass, follow these steps:
1. Press the Power switch to the off position, and then disconnect the USB cable and power cable from the
scanner.
2. Open the scanner lid.
3. Clean the glass by using a soft, lint-free cloth that has been sprayed with a mild glass cleaner.
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.
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. Dry the glass with a dry, soft, lint-free cloth.
5. Reconnect the USB cable and power cable to the scanner, and then press the Power switch to the on
position.
NOTE: If cleaning the top surface of the glass does not remove all dirt and smudges from the glass, you can
also clean the underside of the glass. Cleaning the underside of the glass requires that you disassemble the
scanner. For instructions on how to clean the underside of the scanner glass, go to
