106 Troubleshooting and maintaining Back to TOC
Cleaning the XPA
(Some models only, see "Front panel and accessories comparisons"
on page 3 .) Clean the XPA with a dry, soft cloth. If necessary, spray
the cloth with window cleaner or isopropyl alcohol.
Cleaning the ADF glass
(Some models only, see "Front panel and accessories comparisons"
on page 3 .) You must clean the ADF glass to maintain high-quality
scanning.
To clean the ADF glass
1 Disconnect the power cable from the scanner.
2 Open the scanner lid and locate the ADF glass area on the
scanner glass.
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.
