Cleaning and maintaining
Periodically, the scanner and accessories might need to be cleaned or
to have maintenance, especially if you are seeing marks or smudges
on scanned images.
Cleaning the scanner glass
You might need to clean the scanner glass if the ink on items you are
scanning can be smudged with your hand or items have excessive
amounts of dust or dirt on them. You might also need to clean the
scanner glass if there are smudges or other marks on scanned
images.
To clean the scanner glass
1 Disconnect the power cable from the scanner.
2 Open the scanner lid.
3 Clean the glass using a soft, lint-free cloth sprayed with a mild
glass cleaner.
CAUTION Only use 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.
4 Dry the scanner glass with a dry, soft, lint-free cloth.
5 When finished, reconnect the power cable to the scanner.
Fingerprints or smudges on the underside of the glass do not affect the
appearance of scanned images because this area of the glass is
outside the focal point of the scanner.
