procedure only when necessary.

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

Check Pattern” on page 39.
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.
