Remedy
Wipe the glass with a soft, dry cloth.
(See p. 10-3.)
Clean the document transfer belt
with a soft cloth dampened with a
mild detergent. (See p. 10-4.)
Place a blank sheet of paper on top
of the document. (See p. 3-9.)
If a thin double-sided document is
being copied, the information on the
back side may be reproduced in the
copy. Touch [Light] on the Back-
ground Removal screen to select a
lighter background density. (See
p. 3-58.)
Use the charger-cleaning tool to
clean the electrostatic charger. (See
p. 10-6.)
Correctly position the document
against the document scales. (See
p. 3-9.)
Load the document into the ADF,
and slide the adjustable document
guides to fit the size of the docu-
ment. (See p. 3-7.)
If the document cannot be fed cor-
rectly through the ADF, make cop-
ies by positioning the document on
the original glass. (See p. 3-9.)
Wipe the glass with a soft, dry cloth.
(See p. 10-3.)
Slide the document guides against
the edges of the document.
Flatten the paper before loading it.
Remove the paper from the paper
tray, turn it over, and then load it
again.
Replace the paper with paper that is
not damp.
