Maintenance

With the exception of periodic cleaning, the scanner is virtually maintenance-free. Please read the
following section to learn how to properly maintain the scanner.

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.
