Printed colors are inaccurate

Printed colors are inaccurate
Printed colors are inaccurate
Color adjustment has not been activated in the Ad-
vanced 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 Priority is not selected.
There may be a slight difference in how colors are
printed after Printhead replacement because of indi-
vidual 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 set-
tings or in a different printing environment.

Banding in different colors occurs

Banding in different colors occurs
Cause
The paper feed amount is out of adjust-
ment.
Printing does not proceed smoothly be-
cause print jobs are interrupted during
transmission.
In the Control Panel menu, Adj. Priori-
ty is set to Print Length.
The Printhead is out of alignment.
The Printhead nozzles are clogged.
Streaks may occur if you set the Print
Quality too low.
The type of paper specified in the print-
104
er driver does not match the type loa-
ded in the printer.
Cause
Adjust the feed amount.
(See "Adjusting the Feed Amount.")
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.")
Exit other applications and cancel other print jobs.
Setting Adj. Priority to Print Quality in the Control Panel menu and adjusting the feed amount
may improve results.
(See "Adjusting the Feed Amount.")
Adjust the Printhead alignment.
(See "Automatic Adjustment to Straighten Lines and Colors.")
Print a test pattern to check the nozzles and see if they are clogged.
(See "Checking for Nozzle Clogging.")
Choose a higher level of Print Quality in the Advanced Settings of the printer driver and try
printing again.
Printing in Draft or Standard mode is faster and consumes less ink than in Highest or High
modes, but the printing quality is lower.
(See "Giving Priority to Particular Graphic Elements and Colors for Printing.")
Load paper of the same type as you have specified in the printer driver.
(See "Loading Rolls in the Printer.")
(See "Loading Sheets in the Feed Slot.")

(See "Main Pane (Mac OS X).")
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.
Print a test pattern to check the nozzles and see if they are clogged.
(See "Checking for Nozzle Clogging.")

cation Color Matching Priority in the dialog box.
(See "Layout Sheet (Windows).")
