Do not clean inside the printer
Clean the printheads automatically
If you notice white lines or single-color streaks on the photos you print, the printheads
might need to be cleaned.
To clean the printheads automatically
1. Press Menu on the printer control panel.
2. Select Clean printheads, and then press OK.
3. Following the directions on the printer screen, load paper so the printer can print a
test page after cleaning the printheads. Use Letter or A4-sized plain paper to
conserve photo paper.
4. Press OK to begin cleaning the printheads.
If you still notice white streaks or missing colors on the test page, you might need to clean
the printhead nozzles manually. For more information, see Clean the printhead nozzles
manually.
Note 1 Do not clean the printheads more often than necessary, since the
cleaning uses ink.
Note 2 If a message appears on the printer screen directing you to replace a
printhead, try cleaning the printheads as directed here, first automatically, and
then manually if necessary. If the message still appears on the printer screen after
cleaning, call HP support. If the support staff tell you that the printhead needs to
be replaced, see Replace faulty printheads for more information.
Clean the printhead nozzles manually
If you use the printer in a dusty environment, debris might accumulate on the gold-colored
nozzles and cause printing problems. If you have tried cleaning the printheads
automatically using the Clean printheads procedure from the control panel, and you are
still experiencing image quality problems, you can clean the printhead nozzles manually
using the following procedure.
