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