7. Clean the glass by using a soft, lint-free cloth that has been sprayed with a mild glass
cleaner.
CAUTION: Use only glass cleaner to clean the scanner glass. Avoid cleaners
that contain 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.
Do not spray the glass cleaner directly on the glass. If too much glass cleaner is
applied, the cleaner could leak under the glass and damage the scanner.
8. Dry the glass with a dry, soft, lint-free cloth.

separation pad every 100,000 scans.
The HP Scanner Tools Utility can remind you when service is needed, which depends
on many conditions and might be sooner than this replacement interval.
Replace the feed roller and separation pad
If streaks on scans or paper jams occur repeatedly and cleaning the scanner does not
help, replace the feed roller.
