Maintain the printhead and cartridges
If you are experiencing print quality issues, you might have a problem with the printhead.
NOTE: Turning the printer o improperly can cause print quality problems. To turn the printer o, always
use (the Power button). This allows the printer to cap the printhead and protect it from damage.
●
Clean the printhead if your cartridge is not low on ink and the printout is streaked or has any incorrect or
missing colors.
There are three 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 all 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.
NOTE: The cleaning process takes a few minutes. Some noise might be generated in the process.
●
Align the printer when the print quality diagnostic page shows misalignment or white lines through any
of the blocks of color, or if you are seeing jagged lines in your printouts.
The printer automatically aligns the printhead during the initial setup.
NOTE: Performing the aligning and cleaning procedures unnecessarily can waste ink and shorten the life of
the cartridges.
