Solution 1: Make sure you are using original HP ink cartridges
Solution: Check to see if your ink cartridges are original HP ink cartridges.
HP recommends that you use original HP ink cartridges. Original HP ink
cartridges are designed and tested with HP printers to help you easily produce
great results, time after time.
NOTE: HP cannot guarantee the quality or reliability of non-HP supplies.
Printer service or repairs required as a result of using a non-HP supply are
not covered under warranty.
If you believe you purchased original HP ink cartridges, go to:
Cause: Non-HP ink cartridges were being used.

Solution 2: Check the ink levels
Solution: Check the estimated ink levels in the ink cartridges.
NOTE: Ink level alerts and indicators provide estimates for planning
purposes only. When you receive a low-ink alert, consider having a
replacement cartridge available to avoid possible printing delays. You do not
need to replace the ink cartridges until prompted to do so.
NOTE: The printer can operate with one or more depleted cartridges.
However, printing with depleted cartridges slows the printer and affects the
quality of printed documents. If the black cartridge is depleted, blacks are not
as dark. If a color cartridge is depleted, output is in grayscale. When possible,
replace the depleted cartridge. Do not remove the depleted cartridge until you
have a new ink cartridge available. For information about how to install new
cartridges, see Replace the ink cartridges.
CAUTION: While ink cartridges are not damaged when left outside of the
printer, the printhead does need to have all cartridges installed at all times
after the printer is set up and in use. Leaving one or more cartridge slots
empty for an extended period may lead to print quality problems and possibly
damage the printhead. If you have recently left a cartridge out of the printer
for an extended period, or if you have had a recent paper jam, and have
noticed poor print quality, clean the printhead. For more information, see
Clean the printhead.

Cause: The ink cartridges might have insufficient ink.
