Hi @Charles19501

 

Welcome to the HP Support Community. I'd be happy to assist you with the printhead error. 

 

Let's try these steps to reset the printer - 

 

1) Take out the cartridges. 
2) Unplug the power cord from the printer & wall. 
3) Wait for 30 seconds.  
4) Plug the power cord back into the printer and wall, ensure the printer is plugged into the wall & not to a surge protector. 
5) Insert the cartridges back into the printer.

 

Also, try updating the printer's firmware. Refer to this document for steps - HP Printers - Updating or Upgrading Printer Firmware

 

If the issue still persists, try step#2 from here.  

 

Hope this helps! Keep me posted.
