Start to print a nozzle check pattern to
check the results (& “Checking the print
head” on page 30).
If there are still gaps or the test patterns
are faint, run another cleaning cycle and
check the nozzles again.
Note:
If you do not see any improvement after
cleaning about four times, turn off the printer
and wait for at least six hours. This lets any
dried ink soften. Then try cleaning the print
head again. If quality still does not improve,
one of the ink cartridges may be old or
damaged and needs to be replaced
(& “Removing and Installing Ink Cartridges”
on page 27).

patterns are printed.

that is most evenly printed, with no
noticeable streaks or lines.
7. Select the number for that patch, then
press OK.
8. Enter the numbers for the other patterns
in the same way.
9. When you finish, press OK and you see a
message indicating alignment is
complete.
