• For Other Paper
If the curl on the four corners of the paper is more than 0.1 inch / 3 mm (A) in height, the paper may be
smudged or may not be fed properly. In such cases, follow the procedure described below to correct the
paper curl.
1. Roll up the paper in the opposite direction to the paper curl as shown below.
2. Check that the paper is now flat.
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 inward. In such cases, follow the procedure described below to curl the paper outward within 0.1
inch / 3 mm (B) in height before printing. This may improve the print result.
(C) Printing side
We recommend printing paper that has been curled outward one sheet at a time.
Adjust the setting to prevent paper abrasion.

Adjusting the setting to prevent paper abrasion 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 or the computer.
Print speed may be reduced if you apply the setting to prevent paper abrasion setting.
* Readjust the setting not to prevent paper abrasion once printing is complete. If not, this setting remains
enabled for all subsequent print jobs.
• To set by using the operation panel
Press the Setup button, then select Device settings and Output settings in this order, then set Prevent
abrasion to ON.
