Clean the HP Fax
To ensure that your copies and scans remain clear, you might need to clean the glass
strip or white strip inside the automatic document feeder. You might also want to dust the
exterior of the HP Fax.
Clean the glass strip
Minor debris can accumulate on the white strip located inside the automatic document
feeder.
To clean the glass strip inside the automatic document feeder
1. Unplug the power cord.
NOTE: Depending how long the HP Fax is unplugged, the date and time might
be erased. You might need to reset the date and time later, when you plug the
power cord back in.
2. Lift the cover of the automatic document feeder.
There is a glass strip under the automatic document feeder.
3. Clean the glass strip with a soft cloth or sponge slightly moistened with a nonabrasive
glass cleaner.
CAUTION: Do not use abrasives, acetone, benzene, or carbon tetrachloride on
the glass, since they can damage it. Do not place or spray liquid directly on the
glass. The liquid might seep under the glass and damage the HP Fax.
