Replace the print cartridges
When the ink level for the print cartridge is low, a message appears on the color
graphics display.
Note
You can also check the ink levels by using the HP Director that came with the
HP Image Zone software on your computer. For more information, see
Check
the estimated ink levels
.
When you receive a low-ink warning message on the color graphics display, make sure
you have a replacement print cartridge available. You should also replace the print
cartridges when you see faded text or if you experience print quality issues related to
the print cartridges.
Tip
You can also use these instructions to replace the black print cartridge with a
photo or gray photo print cartridge for printing high-quality color or black-and-white
photos.
