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. 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. HP recommends that you replace any missing cartridges as soon as possible to avoid print quality issues and possible extra ink usage or damage to the ink system. Never turn off the printer when ink cartridges are missing.

Replace the ink cartridges
1. Make sure the printer is turned on.
2. Open the cartridge access door. The carriage moves to the center of the printer. Wait until the carriage is idle and silent before you continue.
3. Press the front of the ink cartridge to release it, and then remove it from the slot.
4.
a. Remove the new ink cartridge from its packaging.
! Do not touch the copper-colored electrical contacts !
b. Pull the orange tab on the wrapper straight back. Make sure that you remove the orange pull-tab completely otherwise, ink might leak from the cartridge. When you remove the plastic wrap, the paper label on the top of the cartridge tears slightly, which is necessary to properly vent the cartridge.
5. Hold the cartridge by its sides, and then twist the protective orange cap counter-clockwise to snap it off the cartridge. You might need to apply some force to move the cap. Do not touch the copper-colored contacts or the ink nozzles. Touching these parts can result in clogs, ink failure, and bad electrical connections.
6. Using the color-coded letters for help, slide the ink cartridge into the empty slot until it clicks securely into the slot.
Make sure that you insert the ink cartridge into the slot that has the same colored letter as the color you are installing.
7. Repeat steps 3 through 5 for each ink cartridge you are replacing.
8. Close the ink cartridge access door.
8. Align the printhead if necessary.
The printer automatically aligns the printhead during the initial setup. However, you might want to use this feature when the printer status page shows streaking or white lines
through any of the blocks of color or if you are having print quality issues with your printouts. Load Letter or A4 unused plain white paper into the input tray first. You can align the printhead from the printer’s control panel, from the HP printer software or embedded web server (EWS).
