Aligning Print Head - Auto head align
Aligning the print head position allows you to print without shifts in the color registration.
There are two ways to align the print head, automatic or manual. First, try adjusting the print head
automatically. If the automatic print head aligning does not work or if you wish, you can adjust the print
head manually. See "Adjusting the Print Head Manually" on page 43.
