Depending on your printing environment, after border-
less printing in which the leading and trailing edge of
the roll is cut automatically, any ink adhering to the cut-

between about 30 seconds and 3 minutes before trying borderless printing again.

Color adjustment has not been activated in the Advanced Set-
tings of the printer driver.
In the Advanced Settings of the printer driver, access Color Settings in
Color Mode to adjust colors.
(See "Main Sheet (Windows).")
Colors have not been adjusted on the computer or monitor.
Refer to the computer and monitor documentation to adjust the colors.
Adjust the settings of the color management software, referring to the
software documentation as needed.
The Printhead nozzles are clogged.
Print a test pattern to check the nozzles and see if they are clogged.
(See "Checking for Nozzle Clogging.")
In the Windows printer driver, Application Color Matching Priori-
ty is not selected.
Click Special Settings on the Layout sheet of the printer driver and se-
lect Application Color Matching Priority in the dialog box.
(See "Layout Sheet (Windows).")
There may be a slight difference in how colors are printed after
Printhead replacement because of individual variation among print-
heads.
Execute color calibration.
(See "Color Calibration Using the Printer Sensor.")
Printhead characteristics gradually change through repeated use,
and colors may change.
Execute color calibration.
(See "Color Calibration Using the Printer Sensor.")
Color may change slightly even on the same model of printer if you
use a different version of the firmware or printer driver, or when
you print under different settings or in a different printing environ-
ment.
Follow these steps to prepare the printing environment.
1.
Use the same version of firmware or printer driver.
(See "Updating the Firmware.")
2.
Specify the same value for all settings items.
3.
Execute color calibration.
(See "Color Calibration Using the Printer Sensor.")
When reinstalling the printer driver, you changed the region selec-
tion of the Media Configuration Tool.
Changing the region selection of the Media Configuration Tool de-
letes the region-specific paper information originally registered on
the printer before installation. Using paper with deleted information
when executing color calibration will prevent the resulting calibra-
tion adjustment value from being applied to all other types of the
paper.
Prepare paper compatible with calibration in the newly selected region
and perform calibration again.
