HP Photosmart C7200 Series - Manual (Page 200)

The print quality of the fax I received is poor
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, contact your
telephone company.
Cause: The sending fax machine is having problems.
Solution: Ask the sender to check their fax machine for any problems.
Cause: The glass or automatic document feeder of the sending fax machine is dirty.
Solution: If you have vertical lines or streaks on the fax, the sender's fax machine
might have dirt or dust on the glass or automatic document feeder. Check with the
sender to see if the glass or automatic document feeder is clean.
Cause: The print head needs to be cleaned.
Solution: Clean the print head, and then print a self-test report. Check the color
blocks in the report for any problems. If the color blocks show print quality problems,
perform a printer alignment.
If the problem persists after cleaning and aligning, contact HP support for help. Go

Some of the pages of a fax I received are faded or blank
Cause: The original might have been loaded incorrectly into the sending fax
machine.
Solution: Ask the sender to check that the fax was sent correctly.
Cause: The HP All-in-One picked up two sheets of paper while printing the fax.
Solution: If the HP All-in-One has only a few sheets remaining, load more paper in
the input tray. If there is plenty of paper in the input tray, remove the paper, tap the
stack of paper against a flat surface, and reload the paper into the input tray.
Cause: The paper loaded in the input tray is not suitable for your fax.
