compatible) to continue printing.

Check the estimated ink levels

You can check the estimated ink levels from the printer software or from the printer control panel.

To check the estimated ink levels from the printer control panel

▲

From the printer control panel, touch or swipe down the tab at the top of the screen to open the
Dashboard, and then touch

(Ink) to check the estimated ink levels.

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 have

to replace the cartridges until prompted to do so.

NOTE:

If you have installed a refilled or remanufactured cartridge, or a cartridge that has been used in

another printer, the ink level indicator might be inaccurate or unavailable.

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 printer 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

CAUTION:

HP recommends that you replace any missing cartridges as soon as possible to avoid print quality

issues and possible extra ink usage or damage to the ink system. Never turn off the printer when cartridges

are missing.
