Problem
Black spots appear on the
copy of a photographic print.
White stripes appear on the
OHP.
The image on the back side of
duplex copies has mottled
blank patches or is smudged.
Cause
Because of high humidity, the
photographic print has stuck
to the exposure glass.
Fragments of paper are stuck
to the OHP.
Missing patches and
smudges are caused by
moisture leaking from the
paper.
When You Cannot Make Clear Copies
Solution
Place the print on the exposure glass in
either of the following ways:
• Place an OHP transparency on the
exposure glass, and then place the
print on the OHP transparency.
• Place the print on the exposure
glass, and then place two or three
sheets of white paper on it. Leave
the ADF open when copying.
Use a dry cloth to wipe any paper
fragments off the back of the OHP.
• Do not install the machine in areas
that are susceptible to low
temperatures.
• Use paper that has been stored
where temperature and humidity
conditions meet the limitations we
recommend. For details about the
paper storage conditions we
recommend, see "Paper Storage",
