There may be a slight difference in how colors are printed after Printhead
replacement because of individual variation among printheads.
Execute color calibration.
Printhead characteristics gradually change through repeated use, and
colors may change.
Execute color calibration.
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 environment.
Follow these steps to prepare the printing environment.
1.
Use the same version of firmware or printer driver.
2.
Specify the same value for all settings items.
3.
Execute color calibration.
When reinstalling the printer driver, you changed the region selection of
the Media Configuration Tool.
Changing the region selection of the Media Configuration Tool deletes
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 calibration adjustment value
from being applied to all other types of the paper.
Prepare paper compatible with calibration in the newly selec-
ted region and perform calibration again.
