Adjustments for Better Print Quality

Adjusting the Printhead

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.

Important

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

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

ment.

(See "Manual Adjustment to Straighten Lines and Colors.") ➔ User's Guide

Note

• Because the results of adjustment vary depending on the type of paper used for adjustment, use the same type of

paper as you will use for printing.

• Use Auto(Standard) if you have switched to another type of paper or if you want the boundaries between colors

to appear as clear as possible.

• Use Auto(Advanced) to fine-tune the space between nozzles or colors if you have switched the printhead or if

clearer printing is required. We recommend Auto(Advanced) for printing at the highest level of quality.

Paper to Prepare

When Using Rolls An unused roll at least 10 inches wide

When Using Sheets Auto(Standard) : One sheet of unused paper of at least A4/Letter size

Auto(Advanced): Six sheets of unused paper of at least A4/Letter size (or one sheet when using A2 or larg-

er)

Perform adjustment as follows.
