Remedy
Wipe the glass with a soft, dry cloth.
(See p. 10-3.)
Clean the left partition glass with the
left partition glass cleaner. (See
p. 10-4.)
Clean the original cover pad with a
soft cloth dampened with a mild de-
tergent. (See p. 10-5.)
Place a blank sheet of paper on top
of the original. (See p. 3-9.)
If a thin double-sided original is be-

copy. Touch [Light] on the Back-
ground Removal screen to select a
lighter background density. (See
p. 3-60.)
Use the charger-cleaning tool to
clean the electrostatic charger. (See

p. 3-9.)
Load the original into the ADF, and
slide the lateral guides to fit the size
of the original. (See p. 3-7.)
If the original cannot be fed correct-
ly through the ADF, make copies by
positioning the original on the origi-
nal glass. (See p. 3-9.)
Clean the left partition glass with the
left partition glass cleaner. (See
p. 10-4.)
Slide the lateral guides against the
edges of the original.
Flatten the paper before loading it.
Remove the paper from the paper
tray, turn it over, and then load it
