To keep your scanner operating at its best, clean it periodically using the following procedure.

Turn off the scanner using its power switch.

Unplug the AC adapter cord from the scanner.

Clean the outer case with a cloth dampened with mild detergent and water.

If the glass surface of the document table gets dirty, clean it with a soft dry cloth. If the glass surface is stained with grease or some other hard-to-remove material, use a small amount of glass cleaner and a soft cloth to remove it. Wipe off all remaining liquid. Do not apply glass cleaner directly on the glass.

Remove the document mat and clean the transparency unit window as described in step 4.

Make sure that no dust builds up on the surface of the document table or the transparency unit window. Dust can cause spots in your scanned images.

Caution:

Do not press the glass surface of the document table with any force. Be careful not to scratch or damage the glass surface of the document table, and do not use a hard or abrasive brush to clean it. A damaged glass surface can decrease the scan quality. Never use alcohol, thinner, or corrosive solvent to clean the scanner. These chemicals can damage the scanner components and the case. Be careful not to spill liquid into the scanner mechanism or electronic components. This could permanently damage the mechanism and circuitry. Do not spray lubricants inside the scanner. Never open the scanner case.
