The copied image is stained.

The Automatic Document
Feeder (optional) or the
Platen Cover (optional) is not
lowered fully.

Lower them fully to block outside light.

The original glass, platen
sheet, scanning area or
guides are dirty.

Clean them.

The copy density is set
darker.

Make the density lighter if you use the
manual copy density mode. Or use the
automatic copy density mode.

A highly transparent original
is used.

Place a blank sheet of paper, the same
size as the original or larger, over the orig-
inal.
