Was the original document
printed on highly translucent

or overhead projector trans-
parencies? Place a blank sheet of paper on top
of the document. (See p. 3-9.)
Is a double-sided document
being copied? If a thin double-sided document is

Load the document into the ADF,
and slide the adjustable document
guides to fit the size of the docu-
ment. (See p. 3-7.)
Is the document incorrectly
positioned in the ADF? 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.)
Is the original glass dirty
(while using the ADF)? Wipe the glass with a soft, dry cloth.
(See p. 10-3.)

guides incorrectly positioned

ument? Slide the document guides against

Was curled paper loaded into
the paper tray? Flatten the paper before loading it.
The printed page is
curled. Was paper that curls easily
(as with recycled paper)
used? Remove the paper from the paper
tray, turn it over, and then load it
again.
Replace the paper with paper that is
not damp.
