Daily Cleaning
To maintain high-quality scanning, you should periodically clean the following:
• Main unit
• Flatbed (Platen glass)
• Pressure Board
• Feeder
CAUTION
• Before you clean the scanner, turn OFF the scanner and computer and disconnect the power cord from the power outlet. Otherwise, an
electrical shock may result.
• Never clean the scanner with any kind of organic solvent, such as alcohol, benzene, or paint thinner. It might cause a fire and electrical shock,
or cause the exterior of the scanner to disfigure or discolor.
• Never spray detergent or water directly onto the flatbed (platen glass). Sprayed liquid can get inside the scanner and soil the light source and
lens.
• Overuse of water and allowing the scanner to become too wet during cleaning can damage scanned documents and cause malfunction of
the scanner.
