How to use the scanner Clean the scanner glass Note Dust and fingerprints affect scanning quality only on the scanning side (dark frame) of the scanner. 1 Disconnect the combination USB and power cable from the scanner. 2 Clean the glass using a soft, lint-free cloth sprayed with a mild glass cleaner. Caution Use only glass cleaner. Avoid abrasives, acetone, benzene, and carbon tetrachloride, all of which can damage the scanner glass. Avoid isopropyl alcohol because it can leave streaks on the glass. Do not spray the glass cleaner directly on the glass. If too much glass cleaner is applied, the cleaner could run to the edges and damage the scanner. 3 Dry the scanner glass using a dry, soft, lint-free cloth. 4 When finished, reconnect the combination USB and power cable to the scanner. Clean the transparent materials adapter If you have a transparent materials adapter for scanning slides and negatives, clean the window in the door and the light window using a slightly-damp, soft, lintfree cloth. Store the scanner To prevent scratches on the scanning side of the scanner, store the scanner in the holder provided. Tip When not in use, use the scanner to display a favorite photo. User's Manual 15
