Cause: The paper is too close to the print cartridge during printing.
Solution: If the paper is too close to the print cartridge during printing, the ink might
be smeared. This can happen if the paper is raised, wrinkled, or very thick, such as
a mailing envelope. Make sure the paper lays flat in the input tray and is not too
wrinkled.
Ink is not filling the text or graphics completely
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.

on page 95 .
Cause: The print paper type setting is incorrect.
Solution: Change the paper type setting to match the type of paper loaded in the
input tray. The HP All-in-One automatically detects the paper type for plain and photo
paper. If you are printing on other types of paper, such as labels or transparencies,
check that you have selected the correct paper type in the HP Photosmart software.
For more information, see:
• “Set the paper type for printing” on page 43
• “Load full-size paper” on page 35
Cause: The copy or print 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.

• “Change the print speed or quality” on page 44
• “Change copy speed or quality” on page 72
The text edges are jagged
Cause: The font is a custom size.
Solution: Some software applications offer custom fonts that have jagged edges
when enlarged or printed. Also, if you want to print bitmapped text, it might have
jagged edges when enlarged or printed.
