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.
For ordering information, see HP supplies and accessories.
Colors do not line up properly
Check printheads
The printheads are automatically aligned when a printhead is replaced.
However, you might notice improvement in the print quality by performing the alignment
procedure yourself. See Maintaining the printheads.
Check graphics placement
Use the zoom or print preview feature of your software to check for gaps in the placement
of graphics on the page.
Lines or dots are missing from text or graphics
Check printheads
The printheads or printhead contact pads might need cleaning. See Maintaining the
printheads.
