If dirt or stripes appear on scanned images or documents, clean the scanning glass and rollers. Clean the scanning glass and rollers 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.

   • Rollers in positions (8), (10), and (12) are turned by the roller in position (11). Turn the roller in position (11) to wipe the rollers.

    If paper jams and double feeds (two papers being fed at the same time) still occur after cleaning the rollers, the rollers may be worn. The rollers need to be changed. Some rollers are replaceable. If the rollers are not replaceable, contact your authorized service representative or dealer to have the scanner serviced.
