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.
CAUTION: 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.
