Cleaning
Regularly cleaning the object glass will ensure that dirt or smudges
will not reduce the quality of your scanned images. Before you
clean the glass, make sure the scanner is turned off and the power
cord is unplugged.
Clean the object glass and document cover; with a soft damp cloth
and a mild detergent or alcohol.
Warning: Do not spray the cleaning fluid directly on the object
glass. Spraying the liquid directly on the glass may cause the liquid
to penetrate the seams around the glass and contaminate the mirrors
and lenses inside the scanner. Please be sure you spray the liquid on
the cleaning cloth and then wipe the glass clean.
