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 at least double the pages of 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. During single-cartridge mode, the product can copy documents, copy photos, and print jobs from the computer.

Replace the ink cartridges
2. Load unused plain white Letter or A4-sized paper into the input tray, if you have not already done so.
7. Hold the cartridge by its sides with the nozzles toward the printer, and then insert the cartridge into its slot. 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.
9. Repeat these steps to replace the other cartridge, if necessary.
11. Follow any prompts on the screen.
12. Wait about 30 seconds for the alignment page to automatically print. If the alignment page did not print automatically, you can align the cartridges manually from the printer software and from the printer display on the product.
Align the cartridges
Aligning the cartridges ensures high-quality output. The HP All-in-One prompts you to align the cartridges every time you install a new cartridge. If you remove and reinstall the same print cartridge, the HP All-in-One will not prompt you to align the print cartridges. The HP All-in-One remembers the alignment values for that print cartridge, so you do not need to realign the print cartridges.
13. Lift the scanner lid.
14. Place the alignment page with the printed-side down on the right-front corner of the scanner glass. See the engraved guide next to the scanner glass for help loading the alignment page.
15. Close the scanner lid.
16. On the printer control panel press OK to begin the scan. The printer automatically aligns the cartridges.
