Maintenance Routine Cleaning Clean the scanner on a regular basis to maintain scanning performance. WARNING • For safety, always turn the power switch OFF and disconnect the power cord before cleaning the scanner and the inside of the feeder. • Do not use spray-type cleaners to clean the scanner. Precision mechanisms may get wet and malfunction. • Never use paint thinner, alcohol, or other solvents to clean the scanner. Doing so may deform, discolor, or dissolve surfaces, or result in a fire or electric shock. Cleaning the Scanner Use a cloth dampened with water and thoroughly wrung out to clean the outside of the scanner, and use a clean dry cloth to wipe the scanner dry. Cleaning the Feed Path Dust or paper particles in the document feed inlet or inside the feeder can cause spots to appear in scanned images. Use compressed air to periodically clean dust and paper particles from the inlet and inside the feeder. In particular, be sure to turn the scanner OFF, and remove the dust and paper particles after scanning a large volume of documents. Cleaning the Scanning Glass and Pressure Board If streaks appear in scanned images, or if scanned documents become dirty, the scanning glass and pressure board may be dirty. Be sure to clean them regularly. 1 Open the feeder gently, and use a clean, dry cloth to wipe the scanning glass and pressure board clean. 60
