If the nozzle check page does not print satisfactorily (for
example, if any segment of the printed lines is missing) there
is a problem with the printer. This could be a clogged ink
nozzle or a misaligned print head. See "Cleaning the Print
Head" for details on cleaning the print head. For information
on aligning the print head, see "Aligning the Print Head".

Cleaning the Print Head

If you find that the printed image is unexpectedly faint or dots in
the printed image are missing, you may be able to solve these
problems by cleaning the print head, which ensures that the
nozzles are delivering ink properly.
You can clean the print head from your computer with the Head
Cleaning utility in the printer software, or from the printer itself
by using the printer's control panel buttons.
