Printhead maintenance
If you are experiencing problems with printing, you might have a problem with the printhead. You
should perform the procedures in the following sections only when directed to do so for resolving print
quality issues.
Performing the aligning and cleaning procedures unnecessarily can waste ink and shorten the life of
the cartridges.
This section contains the following topics:
●

Clean the printhead
If your printed output is streaked or has any incorrect or missing colors, the printhead might need to
be cleaned.
There are two stages of cleaning. Each stage lasts about two minutes, uses one sheet of paper, and
uses an increasing amount of ink. After each stage, review the quality of the printed page. You should
only initiate the next phase of cleaning if the print quality is poor.
If print quality still seems poor after you complete both stages of cleaning, try aligning the printer. If
print quality problems persist after cleaning and aligning, contact HP support. For more information,
see
HP support on page 50.
NOTE: Cleaning uses ink, so clean the printheads only when necessary. The cleaning process
takes a few minutes. Some noise might be generated in the process. Before cleaning the printheads,
make sure you load paper. For more information, see
Load paper on page 11.
Not turning the printer off correctly can cause print quality problems. For more information, see
Turn
the printer off on page 14.
