Make sure you purchase the right ink cartridges for your specific printer and printer region or have your old ones refilled. Cartridges are not compatible between different brands, and often not within the same brand. HP often designs its inkjet hardware to use country-specific consumables. When you unbox a new HP inkjet printer and set it up, you install a set of ink tanks that ship with the printer. As you turn on the device and get ready to use it, an initialization sequence localizes it to the country associated with the ink cartridges you installed. HP recommends that you use original HP ink cartridges.
XL (Extra Large) cartridges cost more but do provide better value in the long run. They will be able to print almost 2 times as many pages as a regular cartridge. Our advice is that if you print often, go with XL. However, ink can dry up. So if you are not a frequent printer, go with the regular cartridges.
Ink level warnings and indicators provide estimates for planning purposes only. When you receive a low-ink warning message, consider having a replacement cartridge available to avoid possible printing delays. You do not have to replace the cartridges until the print quality is unacceptable.
Use the single-cartridge mode to operate the HP All-in-One with only one print cartridge. The single-cartridge mode is initiated when a print cartridge is removed from the print cartridge carriage.

Replace the ink cartridges
3. Lower the output tray, reach inside the printer, grasp the handle, and then lower the ink cartridge access door. The carriage moves to the center of the printer. Wait until the printer is idle and silent before continuing.
7. Hold the cartridge by its sides with the nozzles toward the printer, and then insert the cartridge into its slot at a slight upward angle. Make sure that the icon on the cartridge matches the icon on the slot. The tri-color cartridge goes in the slot on the left, and the black cartridge goes in the slot on the right.
Align the cartridges
11. To achieve the best print quality, it is always useful to align the ink cartridges. You can print the alignment page from the HP Smart app or from the printer software.
