If dirt appears on scanned documents, clean the feed path. Clean the feed path regularly.

• Before you clean the scanner, turn OFF the scanner and computer, and disconnect the power cord from the power outlet. Otherwise, it may cause an electrical shock.
• Never clean the scanner with any kind of organic solvent, such as alcohol, benzene, or paint thinner. This may cause a fire and electrical shock, or cause the exterior of the scanner to disfigure or discolor.
• Never spray mild detergent or water directly on the scanning glass. The spray could penetrate below the glass and contaminate the light source and lenses.
