Remedy
Clean the document glass or the document
glass cover.
Refer to Cleaning the Document Glass
Cover and the Document Glass
page 248.
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
Refer to Auto Background Suppression
page 202.
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 Glass
Cover and the Document Glass
page 248.
Adjust the copy density.
