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 122.
NOTE: Cleaning uses ink, so clean the printhead only when necessary. The cleaning process takes
a few minutes. Some noise might be generated in the process. Before cleaning the printhead, make
sure you load paper. For more information, see Load paper on page 23.
Not turning the printer off correctly can cause print quality problems. For more information, see Turn
the printer off on page 38.
