Printhead problem

HP Office Jet Pro 8710
Microsoft Windows 10 (32-bit)

keep getting message "printhead appears to be missing, not detected or incorrectly installed."


  I have unplugged as instructed and that did not work. 


I replaced all of the cartridges and that did not work. 


It's over a year out of warranty and I don't know where to take it. 


I didn't want to have to buy a new one just yet.  Is approx 2 years the life of an all-in-one now??   Can anyone tell me what to try?  Thanks!

Printhead problem



Welcome to HP support community.


Reseat the printhead up to three times

  1. Open the ink cartridge access door.

  2. Wait until the carriage stops moving before you continue.

  3. Unplug the power cord from the rear of the printer.


    You must disconnect the power cord before reaching inside the printer to avoid risk of injuries or electric shock.

  4. Lift the carriage latch, slightly lift the printhead, lower the printhead back into the carriage, wiggle the printhead left and right, and then lower the carriage latch to lock the printhead into place.

  5. Close the ink cartridge access door.

  6. Reconnect the power cord to the rear of the printer.

  7. Sometimes error messages persist after inserting the printhead. If the error message persists, repeat the steps to reseat the printheadup to three times.

  8. Try to print.
