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.
• Check 4: 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 MENU button, then select Setup, Device settings, and Print settings in this order,
then set Prevent paper abrasion to ON.
Changing the Machine Settings on the LCD
• To set by using your computer
Open the printer driver setup window, and in Custom Settings in the Maintenance sheet, select
the Prevent paper abrasion check box, and then click OK.
To open the printer driver setup window, see How to Open the Printer Driver Setup Window.
• Check 5: If the intensity is set high, reduce the intensity setting and try
printing again.
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 printing from your computer
Reduce the intensity setting in the printer driver and try printing again.
