Printed Colors Are Inaccurate; Banding In Different Colors Occurs - Canon imagePROGRAF iPF6300S User Manual

Troubleshooting

Printed colors are inaccurate

Color adjustment has not been activated in the Advanced Settings
of the printer driver.
Colors have not been adjusted on the computer or monitor.
The Printhead nozzles are clogged.
In the Windows printer driver, Application Color Matching Pri-
ority is not selected.
There may be a slight difference in how colors are printed after
Printhead replacement because of individual variation among
printheads.
Printhead characteristics gradually change through repeated use,
and colors may change.
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.
When reinstalling the printer driver, you changed the region selec-
12
tion 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 infor-
mation when executing color calibration will prevent the resulting
calibration adjustment value from being applied to all other types
of the paper.

If printed sheets are affected by banding in different colors by the trailing edge
(about 20–30 mm (0.8–1.2 in) from the edge), try adjusting the feed amount of
the trailing edge of sheets.
(See "Adjusting Color on the Trailing Edge of Sheets.")
