Cleaning the second-side scanning lens assembly
The second-side scanning lens assembly is located along the left
side of the document cover. The assembly consists of the
mirrored-glass strip, a metal strip, a white-plastic strip, and
rollers. All parts of the assembly must be cleaned to ensure the
best image quality when making copies.
1. With the DADF open, pull the lever that is located at the top of
the document cover.
Part of the document cover pulls away from the assembly,
which allows better access to the second-side scanning lens
assembly.
2. To remove dirt, wipe the mirrored glass, metal strip, both sides
of the white-plastic strip, and the rollers with a soft cloth
moistened with water, and then wipe it dry with a soft cloth.
CAUTION: Do not press heavily on the mirrored glass as this will
result in damage to the film around the glass surface.
