To check the estimated ink levels from the printer control panel

▲From the printer control panel (Home) screen, touch (Ink Information).

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 the print quality becomes unacceptable.

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 www.hp.com/go/ inkusage.

Replace the ink cartridges

If you do not already have replacement ink cartridges for the printer, see Order ink cartridges. Not all cartridges are available in all countries/regions.

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 ink cartridges are missing.

For information on recycling used ink supplies, see HP inkjet supplies recycling program.

To replace the ink cartridges

1.Make sure the printer is turned on.

2.Open the ink cartridge access door.

NOTE: Wait until the print carriage stops moving before proceeding.
