Print Quality Problems - Canon ImageRunner 2545i Reference Manual

Remedy 3 Check for unsuitable paper conditions. Do not use severely curled or wrinkled
paper. (See "Loading Paper," on p. 5-3.) In a high-humidity environment, Special
Mode N may reduce the frequency of paper jams. (See "Preventing Paper Curl
or Jams Caused by a High-humidity Environment," on p. 6-51.)
Cause 5 Paper is preprinted.
Remedy If you are printing on the back side of printed paper, use Special Mode O. (See
"Preventing Paper Jams when Printing on the Back Side of Printed Paper," on
p. 6-53.) Avoid using paper on which color images have been copied, or paper
which has been printed on using a thermal transfer printer (or the reverse side
of such paper).
The machine does not become operational after all the jammed paper
has been removed.
Cause At least one of the covers is left open.
Remedy Close all the open covers and return all the levers to their original position.
Insert each paper drawer as far as it will go. (See "Loading Paper," on p. 5-3.)
