Scanner Cleaning Procedure

The scanner restraint pad and paper feed rollers should be cleaned
when necessary to avoid feed problems.
1. Clean the pad with isopropyl alcohol, wiping downward in the
paper movement direction.
2. Clean the three paper feed rollers using isopropyl alcohol.
Turn the gear train with your thumb to clean the entire surface of
the rollers.
3. Wipe paper dust, ink, or foreign material off the scanner white
reference strip inside the front frame with a clean cloth. If neces-
sary, use isopropyl alcohol.
The scanner lenses and mirrors do not normally require clean-
ing; the microcode compensates for dust on the optical surfaces.
If, however, these surfaces become unusually dirty or the
scanned image becomes fuzzy, remove the scanner and clean
the mirrors and lenses with isopropyl alcohol.
Caution: Do not hold the scanner by the mirrors or supports. If
the supports are bent it can change alignment in the scanner.
Hold the scanner by the plastic.
Note: Do not disassemble any optical components of the scan-
ner.
