Image Quality Problems

Remedy
Clean the document glass or the document
glass cover.
Refer to "Cleaning the Document Glass Cover and the
Document Glass" (P.237).
When copying highly translucent documents,
dirt on the document glass cover shows up in
the copy. Place a sheet of white paper over
the document before copying.
Adjust the copy density or remove the
background paper color before copying.
Refer to "Lighten / Darken" (P.84).
Refer to "Auto Background Suppression" (P.185).
Glossy printing paper easily sticks to the
document glass, and shadows can resemble
dirt in the copy. Place a transparency or
transparent film under the document before
copying.
Clean the narrow glass strip.
Refer to "Cleaning the Document Presser and the
Narrow Glass Strip" (P.237).
Adjust the copy density.
Refer to "Lighten / Darken" (P.84).
Load paper correctly, and align the paper
guides to the paper.
Refer to "Loading Paper in Trays 1 and 2" (P.64).
Refer to "Loading Paper in Tray 5 (bypass)" (P.65).
