Adjusting the Printhead
If printed documents are affected by the following problems, try adjusting the printhead.
● Printing is faint or affected by banding in different colors
Execute Nozzle Check to check for printhead nozzle clogging.
For instructions, see "Checking for Nozzle Clogging (
10.2.2)."
● Printed vertical lines are warped or colors are out of alignment
Execute Head Posi. Adj. to adjust the printhead position.
Normally, execute Auto(Standard) or Auto(Advanced). However, when using special
paper or if printing is not improved after executing Auto(Advanced), try Manual.
(See "Automatic Adjustment to Straighten Lines and Colors (Head Posi. Adj.) (
7.1.2).")
(See "Manual Adjustment to Straighten Lines and Colors (Head Posi. Adj.) (
7.1.3).")
● Printed lines are misaligned
Execute Head Inc. Adj. to adjust the angle of inclination of the printhead.
Even slight misalignment can be corrected.
(See "Adjusting Line Misalignment (Head Inc. Adj.) (
7.1.4).")
● Paper rubs against the printhead, or image edges are blurred
Executing Head Height to adjust the printhead height may improve printing results.
(See "Troubleshooting Paper Abrasion and Blurry Images (Head Height) (
7.1.5).")
