How to use the scanner Warning 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 Disconnect the USB cable and power cable from the scanner. Clean the glass using a soft, lint-free cloth sprayed with a mild glass cleaner, drying the glass with a dry, soft, lint-free cloth. 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. When finished, reconnect the USB cable and power cable to the scanner. Note For instructions on how to clean the underside of the scanner glass, visit www.hp.com/support. ● Clean the transparent materials adapter (TMA) Clean the TMA with a dry, soft cloth. If necessary, lightly spray the cloth with glass cleaner and wipe the TMA. User's Manual 11
