Adjusting the Printhead

Automatic Adjustment to Straighten Lines and Colors

(Head Posi. Adj.)

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 x 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
•
Always make sure the loaded paper matches the type of paper specied on the printer. Adjustment
cannot be completed correctly unless the loaded paper matches the settings.
•
This function is not available with CAD Tracing Paper, CAD Translucent Matte Film, or CAD Clear Film.
If adjustment is not possible as expected using highly transparent lm or similar media, try another type
of paper, or try Manual adjustment.
(→P.606)
Note
•
When printing on special paper, or if printing is not improved after Auto(Advanced), try Manual.
(→P.606)
•
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 ne-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.
•
We recommend using the type of paper you use most often for adjustment.
