Supported ink cartridges

The availability of ink cartridges varies by country/region. The ink cartridges might come in different sizes. To obtain a list of supported ink cartridges for your device, print the self-test diagnostic page and read the information in the ink cartridge status section. (For more information, see Understand the self-test diagnostic page .)

You can find the ink cartridge number in the following places:

•On the self-test diagnostic page (see Understand the self-test diagnostic page).

•On the label of the ink cartridge you are replacing.

•Windows: From the Toolbox, if you have bidirectional communication, click the Estimated Ink Levels tab, scroll to display the Cartridge Details button, and then click Cartridge Details.

•Mac OS: From the HP Printer Utility, click Supply Info from the Information and Support panel, and then click Retail Supplies Information.

NOTE: Ink from the cartridges is used in the printing process in a number of different ways, including in the initialization process, which prepares the device and cartridges for printing, and in printhead servicing, which keeps print nozzles clear and ink flowing smoothly. In addition, some residual ink is left in the cartridge after it is used. For more information see www.hp.com/go/inkusage.

Replace the ink cartridges

You can check the estimated ink levels from the Toolbox (Windows) or the HP Printer Utility (Mac OS). For information about using these tools, see Use device management tools. You can also print the self-test diagnostic page to view this information (see Understand the self-test diagnostic page).
