Check the print cartridges
•
Clean the print cartridges. For more information, see Clean the print cartridges .
• 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
Align the
print cartridges .
• Make sure print 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 device or print cartridge. HP does not
guarantee or support refilled print cartridges. For ordering information, see
HP
supplies and accessories .

Media is not supported for the device
Use only media that is supported for the device and the tray being used. For more
information, see
Understand specifications for supported media .
Media is not picked up
• Make sure media is loaded in the tray. For more information, see Load media . Fan
the media before loading.
• Make sure the paper guides are set to the correct markings in the tray for the
media size you are loading. Also make sure the guides are snug, but not tight,
against the stack.
• Make sure media in the tray is not curled. Uncurl paper by bending it in the
opposite direction of the curl.
• Make sure to fully extend the input tray extension if your device model has an
extension.
Media is not coming out correctly
Remove excess media from the output area. If printed media stacks up outside the
output slot, it can prevent media from properly exiting the device.
