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."
• Printed vertical lines are warped or colors are out of alignment
Execute Head Posi. Adj. to adjust the printhead position.
Normally, execute Auto(Standard), Auto(Advanced), or Auto(Expansion). 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.).")
(See "Manual Adjustment to Straighten Lines and Colors (Head Posi. Adj.).")
• 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).")
Automatic Adjustment to Straighten Lines and Colors (Head Posi. Adj.)
If vertical lines in printed documents are warped or colors are out of alignment, execute Head Posi. Adj.. The printer will
print and read a test pattern, and the Printhead position will be adjusted automatically.
There are three modes for automatic Printhead adjustment: Auto(Standard), Auto(Advanced) and Auto(Expansion).
• Auto(Standard)
Fixes slight distortion and color misalignment.
• Auto(Advanced)
Try adjustment in this mode if Auto(Standard) does not improve printing.
• Auto(Expansion)
Try adjustment in this mode if vertical lines are warped or colors are out of alignment when the printer driver option
High-Precision Photographs or High-Precision Text and Fine Lines is selected.
