Copies are dirty.
Is the document glass or the
document cover dirty?
Clean the document glass or the document
cover.
Refer to "Cleaning the Document Cover and the
Document Glass" (P.231).
Is the document a
transparent type such as a
transparency medium?
When copying highly translucent documents,
dirt on the document cover shows up in the
copy. Place a sheet of white paper over the
document before copying.
Is the document on colored or
rough paper, or a blueprint?
Adjust the copy density or remove the
background paper color before copying.
Refer to "Lighten/Darken" (P.106).
Refer to "Background Suppression" (P.187).
Is the document on glossy
printing paper?
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.
Black lines appear
in copies.
Is the document feeder's
narrow glass strip dirty?
Clean the narrow glass strip.
Refer to "Cleaning the Document Presser and the
Narrow Glass Strip" (P.232).

dark.
Is the copy density set to a
high value?
Adjust the copy density.

Is the copy density set to a

tray?
Load paper correctly, and align the paper
guides to the paper.
