The amount of care necessary depends upon several factors, including the amount of use and the environment. You should perform routine cleaning as necessary. Note: Avoid placing items with sharp edges in the scanner. Doing so can damage the scanner. Before placing an item on the scanner glass, make sure the item is free of wet glue, correction fluid, or other substances that can be transferred to the glass. 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.

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, lint-free cloth. store the scanner To prevent scratches on the scanning side of the scanner, store the scanner in the holder provided.
