HP DeskJet GT 5821

My two years old printer HP DeskJet GT 5821, suddenly started giving error message - "Incompatible Printhead..'. The print head red light is continuously blinking and error icon in the display is also blinking. I tried all remedies given in HP Support site but it has not worked. Please suggest way ahead.

Welcome to HP support community.

 

 Remove, inspect, and then reseat the printheads

The printer might display an error if the printheads are not correctly installed. Only remove the printhead indicated by the printhead icon  on the printer control panel.

  1. Open the exterior door, and then open the printhead access door.

    Access the print carriage
  2. Gently push down on the blue carriage latch.

    The blue carriage latch opens.

    Open the carriage latch

  3. Lightly press down on the printhead to release it, and then pull the printhead out of its slot.

    Removing the printheads

  4. Make sure the plugs on top of the printhead have been removed.

    Pull the orange plugs

  5. Make sure the tape from the printhead contacts has been removed.

       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.

    Remove the tape

  6. 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 printheads

    • Insert the tri-color printhead into the left slot.

    • Insert the black printhead into the right slot.

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

    Close the latch

  8. Close the printhead access door.

  9. Close the exterior door.

    The priming process should continue.

If the issue persists, update the printer firmware
