HP DeskJet GT 5810, 5820 Printers - Replacing Printheads

This document is for HP DeskJet GT 5810, 5811, 5820, 5821, and 5822 All-in-One printers.
Replace printheads that are damaged or no longer functioning properly. Replacement printheads are available from HP Authorized Repair Centers or Service Partners.

Video of replacing the printheads

The following video demonstrates how to replace the printheads.

Step 1: Replace the printheads

Replace the black and tri-color printheads.
note:
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.
    Figure : Example of ink at minimum fill line
    Image: Minimum fill line
  4. Close the output tray extender, and then rotate the output tray left to stow it in the printer.

    Image: Close the output tray
  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.

  7. Gently push down on the blue carriage latch.
    The blue carriage latch opens.

  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.
      caution:
    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.

  9. Open the packages, and then remove the new printheads.

  10. Pull the orange plugs straight up from the tops of the printheads.

  11. Remove the tape from the printhead contacts using the pull tabs.
      caution:
    Do not touch the copper-colored contacts or the ink nozzles. Do not replace the protective tape on the contacts. Handling these parts can result in clogs, ink failure, and bad electrical connections.

  12. Slide the printhead at a slight upward angle into the empty slot, and then gently push up on the printhead until it snaps into place.
    • Insert the black printhead into the right slot.
    • Insert the tri-color printhead into the left slot.

  13. Close the blue carriage latch by pushing down firmly until the latch snaps into place.

      caution:
    Very Important! Do not open the blue carriage latch after printhead installation. Opening the latch might result in severe ink system errors.

  14. Close the printhead access door.
    A blinking P displays on the control panel.
  15. Close the exterior door.
  16. Pull out the output tray, and then raise the tray extender.

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

Aligning the printheads is necessary to achieve the best print quality. After the alignment, the printer begins the process of priming the ink system.
  caution:
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.

    Image: Press and hold the resume button
  2. Lift the scanner lid.
  3. Place the alignment page with the print side down on the right-front corner of the scanner glass, and then close the scanner lid. Position it according to the engraved guides around the scanner glass.

  4. Close the scanner lid.
  5. On the control panel, press the Start Copy Color button .

    Image: Press the color copy button
    The printer aligns the printheads.
  6. The printer starts the priming process. You can still print, scan, and make copies while the printer is priming.
    note:
    The priming process can last up to 45 minutes.
    Priming is complete when the rotating lines stop and a 0 displays on the control panel.
