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) 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.")

(See "Manual Adjustment to Straighten Lines and Colors.")

Even slight misalignment can be corrected.

Paper rubs against the printhead, or image edges are blurred

Automatic Adjustment to Straighten Lines and Colors

If printed vertical lines are warped or colors are out of alignment, execute Head Posi. Adj. to adjust the Printhead

alignment.

There are two modes for automatic Printhead adjustment: Auto(Standard) and Auto(Advanced).

Auto(Standard) will fix most slight image distortion or color misalignment, but if not, try Auto(Advanced).

Use Auto(Standard) or Auto(Advanced) to have the printer print and read a test pattern for automatic adjustment of

the Printhead.

•

This function is not available with Tracing Paper, Translucent Matte Film, or Clear Film.

Important

•

If adjustment is not possible as expected using special media, try another type of paper, or try Manual adjustment.

(See "Manual Adjustment to Straighten Lines and Colors.")
