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.

glass cleaner is applied, the cleaner could leak under the glass and damage
the scanner.

paper that is fed through it. If you use the ADF several times per week, monthly
cleaning is recommended. Set up a cleaning routine that is appropriate for the device.
If streaks exist on scanned documents, cleaning the ADF frame might solve the
problem.
