and colors may change.
Execute color calibration.
(See "Color Calibration Using the Printer Sensor.") âž” P.794
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.") âž” P.917
2.
Specify the same value for all settings items.
3.
Execute color calibration.
(See "Color Calibration Using the Printer Sensor.") âž” P.794
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.
