General tips
Check the ink cartridges
•
Check to make sure that both cartridges are installed and functioning correctly.
• Ink cartridges might need to be cleaned. For more information, see To clean ink
cartridges automatically.
• Ink 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 Work with ink cartridges.
• Whenever you install a new ink cartridge, you should align the ink cartridges for
the best possible print quality. If the printout is grainy, has stray dots, jagged
edges, or the ink is bleeding into another color, you can realign them through
Toolbox or the print driver (Windows), HP Utility (Mac OS), or the Toolbox
software for PDAs (Windows Mobile). For more information, see Align the ink
cartridges.
• Dropping or subjecting the ink cartridges to impact might cause temporary
missing nozzles in the ink cartridge. To resolve this problem, leave the ink
cartridge in the printer for 2 to 24 hours.
• Use the appropriate ink cartridge for the project. For best results, use the HP
black ink cartridge to print text documents and use the HP photo ink cartridge to
print color or black and white photos.
• 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 or ink cartridge. HP does not
guarantee or support refilled ink cartridges. For ordering information, see HP
supplies and accessories.
Check the paper quality
The paper might be too moist or too rough. Make sure the media meets HP
specifications, and try to print again. For more information, see Media specifications.
Check the type of media loaded in the printer
Make sure the tray supports the type of media you have loaded. For more information,
see Media specifications.
Check the rollers in the printer
The rollers in the printer might be dirty, causing lines or smudges to appear on the
printout. Turn off the printer, remove the battery, and then disconnect the power cord.
Clean the output rollers in the printer with a lint-free cloth lightly dampened with water,
and then try to print again.
Check the printer location and length of USB cable

and other such devices) can sometimes cause slight distortions to printouts. Move the
