Cleaning the Print Head
If you find that the printed image is unexpectedly faint or that
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 using the Head
Cleaning utility in the printer software, or from the printer itself
by using the printer’s control panel buttons. For more in formation
about the control panel buttons, see your online Reference Guide.
Note:
❏Print head cleaning uses both color and black ink. To avoid wasting
ink, clean the print head only if print quality declines. For exam ple,
if the printout is blurry or the color is incorrect or missing.
❏Use the Nozzle Check utility first to confirm that the print head
needs to be cleaned. This saves ink.
❏You cannot clean the print head while the B black or A color ink
out light is flashing or on. Replace the appropriate ink cartridge first.
❏Do not start the Head Cleaning or Nozzle Check utility while
printing is in progress; otherwise, your printout may be marred.
