Cleaning the Print Heads

If you find that the printed image is unexpectedly faint, or dots
in the printed image are missing, you may be able to solve
these problems by cleaning the print heads, which ensures that
the nozzles are delivering ink properly.
You can clean the print heads from your computer using the
Head Cleaning utility in the printer software.
If you are using DOS or you cannot clean the print heads with
this utility, you can use the printer's control panel instead. For
more details, see "Cleaning the Print Heads" in Appendix A.
Note:
G
Print head cleaning uses ink. To avoid wasting ink, clean the
print heads only if print quality declines.
G
Use the Nozzle Check utility to confirm that the print heads need
to be cleaned.
G
Do not start the Head Cleaning or Nozzle Check utility while
printing is in progress; otherwise your printout may be marred.
