Aligning the Print Head

Aligning the print head is the most important thing you can do to ensure the
best print quality. If banding appears on your prints, if they look grainy or
blurry, or you see misregistration or "ghosting," you need to align the print
head.
Although you can align the print head using the printer utility software, it's
best to align from the control panel. This will do the most thorough job in
the shortest time, and it's all automatic.
If you haven't already done so, it's a good idea to run a nozzle check before
aligning the print head (page 75). This ensures that the print head alignment
patterns print correctly.
Follow these steps to align the print head using the control panel:

paper.
