Missing patches and
smudges are caused by
moisture leaking from the

• Do not install the machine in low-
temperature areas.
• 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 page 240
