Check the page-orientation setting
Make sure the media size and page orientation selected in the application match the
settings in the printer driver. For more information, see
.
Check the device location and length of USB cable
High electromagnetic fields (such as those generated by USB cables) can sometimes
cause slight distortions to printouts. Move the device away from the source of the
electromagnetic fields. Also, it is recommended that you use a USB cable that is less
than 3 meters (9.8 feet) long to minimize the effects of these electromagnetic fields.
If the above solutions do not work, the problem may be caused by the inability of the
application to interpret print settings properly. See the release notes for known
software conflicts, refer to the application's documentation, or contact the software
manufacturer for specific help.

General tips
Check the print cartridges
•
Check to make sure that both cartridges are installed and functioning correctly.
Print cartridges might need to be cleaned. See Cleaning the print cartridges. Print
cartridges might have run out of ink. Replace any empty cartridge. Try removing
and reinstalling the cartridges, making sure they snap firmly into place. For more
information, see
.

Whenever you install a new print cartridge, you should align the print cartridges for
the best possible print quality. If your printout is grainy, has stray dots, jagged
edges, or the ink is bleeding into another color, you can realign them through the
Toolbox or printer driver (Windows), HP Printer Utility (Mac OS), or Toolbox
software for PDAs (Pocket PC and Palm OS). For more information, see
•
Dropping or subjecting the print cartridges to impact might cause temporary
missing nozzles in the print cartridge. To resolve this problem, leave the print
cartridge in the device for 2 to 24 hours.
