Warning Be careful not to drop the print cartridges. This can damage them, making them unusable.

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.

To find out the reorder number for all the print cartridges that your HP all-in-one supports, see Order print cartridges. To order print cartridges for your HP all-in-one, go to www.hp.com.
