Cause
Paper is curled.
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.
(1)
(3) Check to see that the paper curl is 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.
Note
Depending on the media type, the paper may be
smudged or may not be fed properly even if it is not
curled.
In such case, follow the procedure described above
to curl the paper before printing.
This may improve the print result.
