Cleaning the Print Head
If your printouts are unexpectedly light, or dots or lines are missing, you may need
to clean the print head. This unclogs the nozzles so they can deliver ink properly.
Print head cleaning uses ink, so clean it only if quality declines.
Caution: When you don’t turn on your printer for a long time, print quality can
decline, so turn it on at least once a month to maintain good print quality.
This section explains how to clean the print head using the Auto Nozzle Check and
Cleaning utility and the Head Cleaning utility.
Note: You can also clean the print head by holding down the H ink button on the
printer for three seconds (when the red H ink light is off).
