parent material like a transparency?
Is the document colored, of a rough
texture or a blueprint?

ing paper?

light?
Is the copy density set to Light?

Remedy
Turn the power off without unnecessarily
inserting or removing a tray. Wait several
seconds and then turn the power switch
on. Make sure that the machine is online
(ready to receive data) and then insert or
remove the tray.
Clean the document glass or the docu-
ment cover.
"3.3 Cleaning the Copier" (P. 62)
If the document is highly transparent,
marks on the document cover will be
copied. Place a white sheet of paper on
the document and make a copy.
Either adjust the copy density or image
quality and then retry copying.
See "3.16 Selecting the Original Type -
Original Type" (P. 365), "3.18 Adjusting
Copy Density and Contrast - Lighter/
Darker/Contrast" (P. 371) of "Part 2
Copier".
Glossy printing paper easily sticks to the
document glass, and shadows are
sometimes copied and reproduced as
dirt. Place a transparency or highly
transparent film under the document and
retry copying.
Adjust the copy density.
See "3.18 Adjusting Copy Density and Con-
trast - Lighter/Darker/Contrast" (P. 371) in
"Part 2 Copier".
Align the edges of the paper, and load
the paper again so that is flush against
the tray corners.
