Video overview

Replace the ink cartridges

Open the ink cartridge access door, and then install new ink cartridges.
  1. Press the Power button to turn on the printer, if it is not already on.
  2. Place your fingers into the slot on the left side of the printer, and then gently lift up to open the cartridge access door. The carriage moves to the cartridge access area. Wait several seconds until the carriage is idle and silent before you continue.

  3. Press the tab inward on the front of the old cartridge to release it, and then pull up on the cartridge to remove it from the slot.

  4. Remove a new cartridge from its package, and then pull the orange pull-tab straight back.
      caution:
    Make sure that you remove the orange pull-tab and plastic wrap completely before you twist the orange cap in the next step. 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.

      caution:
    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. Turn the cartridge so that the cartridge contacts face downward, and then match the label color with the color dot on the carriage.
  7. Slide the cartridge into its slot, and then gently press the cartridge down until it is firmly seated.

  8. If the cartridge does not firmly seat, remove the cartridge from the printhead. Gently bend the tab away from the cartridge, and then reinsert the cartridge into the printhead.

      caution:
    Be careful not to bend the tab out more than 1.27 cm (0.5 in). Moving the tab too far might damage the cartridge or cause the tab to break off.
  9. Repeat these steps to install all the new cartridges.
  10. Close the cartridge access door. The printer automatically aligns the cartridges.
