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.
You can check the estimated ink levels from the printer control panel, printer software or the embedded Web server (EWS). 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.
To check the estimated ink levels from the printer control panel:
– From the Home screen, press the Setup button (wrench icon).
– Using the buttons on the right, select Ink Information, and then select Estimated Ink Levels.

Replace the ink cartridges.
Remove the old cartridge
2. Open the cartridge access door.
Locate the two slots on the sides of the printer. Place your fingers in the slots, and then lift to open the ink cartridge access door. The carriage moves into the carriage access area. Wait until the carriage is idle and silent before you proceed.
Insert the new cartridge
4. Remove the new ink cartridge from its packaging by pulling the orange pull-tab straight back to remove the plastic wrap from the ink cartridge. Make sure you remove the orange pull-tab completely. When you remove the plastic wrap, the paper label on the top of the cartridge tears slightly, which is necessary to vent the cartridge. Do not touch the copper-colored electrical contacts and ink port.
6. Hold the ink cartridge so that the ink cartridge contacts are facing down and toward the printer. Match the colored dot on the ink cartridge with the dot of the same color on the carriage. Slide the new ink cartridge into its slot, and then gently press the ink cartridge down until it clicks into place and is seated firmly in the slot.
7. Repeat step 3 to 6 for each ink cartridge you are replacing.
Align the printhead only if necessary.
The printer automatically aligns the printhead during the initial setup. However, you might want to use this feature for print quality issues in printouts where straight lines look wavy or jagged. You can align the printhead from the printer’s control panel, from the Toolbox (Windows) or HP Utility (OS X) and from the embedded web server (EWS).
