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. Unlike other inkjet manufacturers, 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. You’ll usually install both the black and tri-color cartridges in the HP Officejet, but you can also leave one ink cartridge carriage empty (single-cartridge mode). During single cartridge mode, the printer can copy documents, copy photos, and print jobs from the computer.

Replace the cartridges
8. Hold the ink cartridge by its sides with the nozzles toward the printer, and then insert the new ink cartridge into its slot. Push the ink cartridge forward into its slot until it snaps into place. Repeat these steps to replace the other ink cartridge, if necessary. Make sure the ink cartridge is inserted in the correct slot.
12. Press OK to align the ink cartridges. An alignment page prints. Scanning the alignment page allows the printer to align the ink cartridges and provide the best print quality.
