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.
Note
If dirt is difficult to remove, try gently wiping with a soft cloth moistened with a small amount
of neutral detergent.
