Step 1: Replace the printheads

Replace the black and tri-color printheads.
Priming cannot begin until new tri-color and black printheads are installed at the same time into the printer. An E-8 error occurs if only one new printhead is installed in the printer.
  1. Turn on the printer.
  2. Make sure paper is loaded in the printer.
  3. Make sure that all ink levels are above the minimum fill line.

  4. Close the output tray extender, and then rotate the output tray left to stow it in the printer.

  5. Make sure the ink valve is unlocked. Locking the ink valve might cause ink to drip while replacing the printheads.

  6. Open the exterior door, and then open the printhead access door.
    If the carriage does not move to the center of the printer, reach inside and manually move it to the center.

  8. Lightly press down on the tri-color printhead to release it, and then pull the printhead out of its slot. If a printhead is difficult to remove, push up on the blue latch to aid in removal.
    Repeat these steps for the black printhead.
    Keep the printhead upright during removal to prevent ink from leaking. Do not touch the printhead towers (the nozzles on top of the printhead), as they might contain residual ink.

Step 2: Align the printheads and then prime the ink system

Do not move or disconnect power from the printer during the priming process.
  1. On the printer control panel, press and hold the Resume button for 3 seconds.
    The alignment starts when the blinking P becomes a blinking A.
    The printer prints an alignment page.
