Problem Suggested Solution
The edge of the
original image is
deleted from the
copies. • Edge deletion on all sides of the copy is
normal, and is greatest on the lead edge of the
copy. Set the Edge Erase feature, Variable
Erase option, to 4 mm to minimize the deletion.
Select the size for the original document in the
Added Features tab and an appropriate setting
from the Reduce/Enlarge option.
• Moisture may be present in the paper. Load a
fresh supply of paper into the trays.
• Some deletions may be caused by small pieces
of paper remaining in the digital press with
scanner components after a paper jam has
been cleared. When clearing a paper jam, be
sure to look for and remove any paper
fragments.
Copies made from
photographs show
color or background
on output edges Most emulsions used to develop photographs have
color. Sometimes this color shows on the border of
the photograph. To prevent the color from being
copied as part of the image or as background, use
the Edge Erase feature on the Added Features tab
to deliberately erase the unwanted color or
background.
Copies made using
the 100% Reduce/
Enlarge feature do not
include the entire
image along the edge
of the document. Select the Original Input feature and program the
exact size of the dark bordered document that you
wish to copy.
