Hi @Rodbryan

Welcome to the HP Support Community. 

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. Download and install the firmware from this link. 

Hope this helps! Keep me posted.
