Cause
Action
Paper Feed Roller is dirty.
You may need to clean the Paper Feed Rollers of the Auto Sheet Feeder.
Cleaning the Paper Feed Roller of the Auto Sheet Feeder consumes it, so
perform this procedure only when necessary.
For details on cleaning the Paper Feed Roller, see “Cleaning the Paper Feed
Rollers (Roller Cleaning)” on page 37.
Inside of the printer is dirty.
When performing duplex printing, if the inside of the printer is stained with
excess ink, printed paper may become smudged.
See “Cleaning the Inside of the Printer” on page 38 to clean the inside of the
printer.

When performing Borderless Printing, print quality may be reduced at the top
and bottom edges of the paper. Make sure that the paper you are using is
suitable for Borderless Printing.
For details, refer to the Printer Driver Guide on-screen manual.
Paper is curled.
For Plain Paper
Turn the paper over and reload it to print on the other side.
Leaving the paper loaded in the Auto Sheet Feeder for a long time may cause
the paper to curl. If this happens, load the paper with the other side facing up. It
may resolve the problem.
We recommend putting unused paper back into the package and keep them on
a level surface.
For Other Paper
If you are using paper with either any of the corners or the whole printing
surface curled, the paper may become dirty, not feed properly, or both. Use such
paper after correcting paper curl as follows.
(1) With the printing side (A) facing up, cover the paper with a
fresh sheet of plain paper to avoid staining or scratching the
surface.
(2) Roll up the paper in a direction opposite to paper curl as
seen below.
(3) Check to see that the paper curl is corrected to within
approximately 0.08 to 0.2 inches / 2 to 5 mm (B) in height.
We recommend printing curl-corrected paper one sheet at a time.
