Cleaning the scanner
To keep your scanner operating at its best, you should clean it
periodically, as described below.
1. Unplug the power cord.
2. Clean the outer case with mild detergent and water.
3. If the glass of the document table gets dirty, clean it with a
soft dry cloth. If the glass 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.
Be sure that there is no dust on the glass of the document table.
Dust can cause spots in your scanned image.
