If print quality does not improve by standard print head cleaning, try print head deep cleaning,

After print head deep cleaning finishes, print the nozzle check pattern to

When one of the ink tanks does not print, see “Replacing Ink Tanks” on
page 36.

If the problem remains, make sure that ink remains in the ink tank, turn
off the printer's power for at least 24 hours, and then perform deep
cleaning of the print head again.

If the problem still remains, the print head may be damaged. Contact
