Print quality troubleshooting
If you are having problems with print quality, try the solutions in this section and observe
the following guidelines:
• Replace refilled or empty cartridges with genuine HP print cartridges.

correct for the paper and the task.

papers for printing and copying” on page 32 .

Clean the print cartridges automatically. For more information, see “Clean the
print cartridges” on page 85 .
• If you are missing lines when you print, clean the electrical contacts. For more
information, see
“Clean the print cartridge contacts” on page 85 .
• Replace the print cartridge. For more information, see “Replace the print
cartridges” on page 79 .
• If the self-test does not show a problem, investigate other causes, such as the image
file or software program.

the HP All-in-One.
Cause: The print cartridges need to be cleaned.
Solution: Print a self-test report to determine if there is a problem with the print
cartridges. If the self-test report shows a problem, clean the print cartridges. If the
problem persists, you might need to replace the print cartridges.
