Problem Cause Solution
The image on the back side of
duplex copies has mottled
blank patches or is smudged.
Missing patches and
smudges are caused by
moisture leaking from the
paper.
• 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",
About This Machine .
• Install the Optional anti-humidity
heater. For details about the anti-
humidity heater, contact your
service representative.
