Printed Surface Is Scratched/Paper Is Smudged
Cause
Printing on inappropriate type of paper.
Paper is curled.
Printing on thick paper.
Printing beyond the recommended
printing area.
144 Troubleshooting
Check to see if the paper you are printing on is not too thick or curled.
See "Paper Handling" on page 21 to make sure that the paper you are using
is suitable.
If the paper is curled, see "Paper is curled." on page 144 to correct paper
curl.
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 "Printing Area" in the User's Guide on-screen manual.
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.
Selecting the Prevent paper abrasion setting will widen the clearance between
the Print Head and the loaded paper. If you notice abrasion even with the media
type set correctly to match the loaded paper, set the machine to prevent paper
abrasion by using the Operation Panel on the machine or the printer driver.*
* Deactivate the Prevent paper abrasion setting once printing is complete. If
not, this setting remains enabled for all subsequent print jobs.
Setting with the Operation Panel on the machine
Press the Menu button, select Maintenance/settings, Device settings, and
Print settings in this order, and then set Prevent paper abrasion to ON. For
details, refer to "Device Settings" in the User's Guide on-screen manual.
Setting with the printer driver
Refer to "Print Results Not Satisfactory" in the User's Guide on-screen
manual.
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.
