Spin the rollers while wiping them clean with a firmly
wrung cloth dampened with water or a mild detergent.
There are 18 roller positions, as shown in the diagram below.
NOTE
• Use cotton swabs to clean the rollers in locations that are too narrow
for your fingers, such as a, b, j, n, o, and p.
• Rollers in positions b, d, e, k, and p are turned by the roller in
position e. Turn the roller in position e to wipe the rollers.
• Rollers in positions m and n comprise two rollers each, an upper
roller and a lower roller.
• Do not force the rollers if they will not turn. In this case, wipe dirt only
off of the exposed area.
4
Use cotton swabs to clean the entire scanning glass. There
are two scanning glass areas, one on each side. Use a
cotton swab to wipe dirt from the entire surface of each.
