You can check the estimated ink levels from the printer printer control panel:
– From the Home screen on the product control panel, scroll to and touch the Supplies button. The status of all supply items is listed on the screen.
– To print or view a report of the status of all supply items, including the genuine HP part number for reordering the supply, touch the Manage Supplies button. Touch the Supplies Status button, and then touch either the Print or View button.
– Check the percent of life remaining for the cartridges.
Print quality problems can occur when using an ink cartridge that is at its estimated end of life. The supplies status page indicates when a supply level is very low. After an HP supply has reached the very low threshold, HP’s premium protection warranty on that supply has ended. Ink level warnings and indicators provide estimates for planning purposes only. When you see a low-ink warning or indicator, consider having a replacement ink cartridge available to avoid possible printing delays. You do not have to replace the ink cartridges until the print quality is unacceptable.
Make sure you purchase the right ink cartridges for your specific printer. Cartridges are not compatible between different brands, and often not within the same brand. Hewlett-Packard cannot recommend the use of non-HP supplies, either new or remanufactured. Because they are not HP products, HP cannot influence their design or control their quality. If you are using a refilled or remanufactured ink cartridge and are not satisfied with the print quality, replace the cartridge with a genuine HP ink cartridge.
