3. 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.

Maintain the automatic document feeder (ADF)
The ADF requires periodic maintenance depending on the amount of use and the type
of paper that is fed through it. Use an HP paper-path cleaning cloth to clean the ADF
when vertical streaks appear in images scanned by the ADF, when paper used in the
ADF is dusty or dirty, or when the environment is dusty. If you use the ADF several times
per week, monthly cleaning is recommended. Set up a cleaning routine that is appropriate
for the scanner.
Use the following methods to maintain the ADF:
• Clean the paper path
• Clean the ADF window
• Clean the feed roller
• Replace the feed roller and separation pad
Clean the paper path
If scanned images have streaks or scratches, use the HP paper-path cleaning cloth to
clean the paper path.
