Step three: Clean the document feeder glass
Dust might appear on the underside of the glass, but this cannot be cleaned and it has no effect on the copy or scan quality.
1. Open the scanner lid and locate the one-inch strip of glass to the left of the main scanner flatbed glass.

2. Use a soft, lint-free cloth moistened with water to clean the document feeder glass. Some models use an upper document feeder glass similar to the lower one. In this case, perform this cleaning step for both the lower and upper document feeder glass.
If needed, lens cleaner or nonabrasive glass cleaner can be applied to the cloth before cleaning the glass. Spray only onto the cloth and not directly onto the glass or device. Do not spray water or glass cleaner on the glass as it can seep under it and possibly damage the printer. Do not use abrasives, acetone, benzene, ethyl alcohol, or carbon tetrachloride on the glass; these can damage it and/or leave residue on the glass resulting in degraded copy/scan quality.
3. On the underside of the scanner lid above the strip of document feeder glass, use a soft, lint-free cloth moistened with water to clean the upper white strip and metal strip (if applicable). In some cases, this is a glass strip similar to the document feeder glass.
Do not scrub or use paper-based wipes as this can scratch the surface.
4. Dry the document feeder glass and upper strip with a soft, dry cloth to prevent spotting and then try again to copy or scan.
