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.
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 media.
Not turning the printer off correctly can cause print quality problems. For more
information, see
Turn off the printer.

Print and evaluate a print quality report
Print quality problems can have many causes: software settings, a poor image file, or the
printing system itself. If you are unhappy with the quality of your prints, a Print Quality
Diagnostic page can help you determine if the printing system is working correctly.
