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 Rear Tray 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 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 in “For Other Paper” to curl
the paper before printing.
This may improve the print result.
Inappropriate Paper Thickness Lever
setting. Adjust the position of the Paper Thickness Lever according to the type of paper
you are printing on.
See “Paper Handling” on page 12.
Depending on the printing content, the printing surface may become scratched
even for the types of paper to set the lever to the left. In this case, set the Paper
Thickness Lever to the right.
* Reset the Paper Thickness Lever to the left when you finish printing. If the
lever is not set back to the left, the inside of the machine is more likely to get
dirty due to the wider clearance between the print head and the loaded paper.
It may also reduce print quality.
Note
If the corners or edges of the paper are smudged, try to print with the Paper
Thickness Lever set to the right.
Printing graphics with the intensity
setting set too high. Especially if you are using plain paper to print images with high intensity, the
paper may absorb too much ink and become wavy, causing paper abrasion.
When copying, see “Changing the Copy Settings” on page 19 and reduce the
INTENSITY setting. Then try printing again.
When printing from your computer, refer to “Print Results Not Satisfactory” in the
User’s Guide on-screen manual.
Printing beyond the recommended
printing area. If you are printing beyond the recommended printing area of your printing paper,
the lower edge of the paper may become stained with ink.
Resize your original document in your application software.
For details on recommended printing area, refer to “Printing Area” in the User’s
Guide on-screen manual.
