Cause: The sending fax machine is having problems.
Solution: Ask the sender to check their fax machine for any problems.
Cause: The phone line connection is noisy. Phone lines with poor sound quality
(noise) can cause print quality problems.
Solution: If the failure was due to noise on the phone line, contact the sender to
have them resend the fax. The quality might be better when you try again. You can
check the sound quality of the phone line by plugging a phone into the telephone wall
jack and listening for static or other noise. If the problem persists, turn Error
Correction Mode (ECM) off and contact your telephone company.
To change the ECM setting from the control panel
1. Press Setup.

Cause: The print cartridges need to be cleaned or might be out of ink.
Solution: Check the estimated ink levels remaining in the print cartridges. If the
print cartridges are low or out of ink, you might need to replace the print cartridges.
If there is ink remaining in the print cartridges, but you are still noticing a problem,
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.

Cause: The print or copy quality setting on the HP All-in-One is set too low.
Solution: Check the quality setting. Use a higher quality setting to increase the
amount of ink used for printing or copying.
To change the copy quality
1. Make sure you have paper loaded in the input tray.
2. Load your original print side down on the right front corner of the glass or print
side up in the document feeder tray.
If you use the document feeder tray, place the pages so that the top edge of the
document goes in first.
