The image quality gradually degrades on
successive copies, or copies made with set-
tings used previously are significantly worse
than copies you are making now.
The internal process control function of the
copier/printer has degraded.
Place a white sheet of paper on the Docu-
ment Glass and run 35 blank copies using
Full Color in the Output Color feature. Make
a copy of the document again. The copy
quality output should be improved. If not,
ensure that the image quality selections,
which may have been misadjusted previ-
ously to remedy the initial problem, are set to
the appropriate levels.
Adjust the Auto Screening Adjustment fea-
ture in the Tools Mode. Contact your System
Administrator or refer to the System Admin-
istration Guide.
Copies have dark bands on the lead edge
and a corner when 100% Reduce/Enlarge is
selected.
The bands may be caused by curled edges
on the document or by misregistration of the
document on the Document Glass.
Ensure that the document is registered cor-
rectly.
Ensure that the Edge Erase is at No Erase
(2 mm). Increasing the amount of Edge
Erase should remove more of the dark
bands but could cause image loss.
Copies have dark bands on the lead edge
and a corner when 100% Reduce/Enlarge is
selected and the DADF is used.
The bands may be caused by curled edges
on the document or by misregistration of the
document by the Duplex Automatic Docu-
ment Feeder (DADF). Ensure that the Edge
Erase is at No Erase (2 mm). Increasing the
amount of Edge Erase should remove more
of the dark bands but could cause image
loss.
Corner Shift appears in the wrong area on
the copy.
If the document is positioned on the Docu-
ment Glass in the short edge feed direction,
and the paper used for copying is in the long
edge feed direction, the copy will appear to
be positioning the Corner Shift selection in
the wrong corner. Corner shift selections are
referenced from the Document Glass loca-
tion. Refer to chapter 5, “Added Features,”
for illustrated examples.
NOTE: Corner Shift is also intended only for
documents that are smaller than the copy
paper selected.
