Output is faded or dull colored
Check the print mode
The Fast Normal and Fast modes in the printer driver allow you to print at a faster rate,
they are good for printing drafts. To get better result, select Normal or Best.
See Changing print settings.
Check the paper type setting
When printing on transparencies or other special media, select the corresponding media
type in the printer driver. See Printing on special and custom-size media.
Check the ink cartridges
If lines in the text or image are broken or do not print properly, one or more of the ink
cartridges may have run out of ink or are defective. Replace these cartridges with
new ones.

Wrong colors are printing
Check print settings
Make sure Print in Grayscale is not selected in the printer driver.
Check the printheads

See Maintaining the printheads.
Printout shows bleeding colors
Check print settings
Some media type settings (such as Transparency Films and Photo Papers) and print
quality settings (such as Best) require more ink than others. Choose different print
settings in the printer driver, make sure you select the correct media type. See Changing
print settings.
Check ink cartridges
Make sure ink cartridges have not been tampered with. Refilling processes and the use of
incompatible inks can disrupt the intricate printing system and result in reduced print
quality and damage to the printer. HP does not guarantee or support refilled ink cartridges.
