Problem
Copies have dark bands on
the lead edge and a corner
when 100% Reduce/Enlarge
is selected and the DADF is
used.
Corner Shift appears in the
wrong area on the copy.
Large black borders appear
on the copies with
documents smaller than the
copy paper size.
The image density of the
copy seems lighter toward
the trail edge.
Copies made from a
newspaper, a map, or a
photograph have
background when Original
Type is defined as Maps or
Photo.
It is difficult to perform
secondary operations on
the copies, such as writing
on them or using
adhesives.
Greyish spots appear when
scanning a glossy photo or
glossy original.

The bands may be caused by curled edges on the document or by
misregistration of the document by the 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.
Ensure the document is positioned on the Document Glass and the
correct Corner Shift is selected.
• No shift is selected. Select the Auto Center feature to eliminate the black
borders.
• Also, select the Auto Center feature to eliminate the black borders for digital
press with scanners equipped with the Duplex Automatic Document Feeder
(DADF).
This defect is noticeable only when the input document has large
solid areas. To reduce or eliminate this defect, select the Photo option
in the Original Type feature of the Image Quality tab.
• The DocuColor 6060 digital press with scanner detects low densities of color
and reproduces them. This is especially true with the Maps and Photo options.
• Use the Background Erase option in the Image Tone Presets feature in the
Image Quality tab.
• Newspaper show-through can be reduced or eliminated by backing the
document with a black sheet of paper.
• The background can be reduced or eliminated by adjusting the Lighten/Darken
feature toward lighten.
This problem is caused by the oil used in the fusing process. The
problem can be reduced or eliminated by setting the copies aside for
one or two hours before performing a secondary operation on them.
Rubbing the copy surface with a soft, clean cloth or eraser may also
help.
Place a transparency on the Document Glass then place the glossy
photo or glossy original face down on the transparency to reduce the
glare.
