Note:
Make sure that paper is not loaded into the front manual feed slot
and the front printer cover is closed before using the Head Cleaning
utility.
Below are two sample nozzle check patterns:
Good sample
Print head needs to be cleaned
The above sample is in black and white, but the actual check pattern prints
in color.
If the nozzle check page does not print satisfactorily, you may
need to repeat the head cleaning and print the nozzle check
pattern again.
& See "Cleaning the Print Head" on page 252
Note:
❏ If print quality has not improved after repeating this procedure four
or five times, turn the printer off and leave it alone overnight. Then,
do the nozzle check again, and repeat the head cleaning if necessary.
❏ If the print quality still has not improved, at least one of your ink
cartridges may be old or damaged and may need to be replaced.
