Hi @Dave_fr

Welcome to the HP Support Community. I'd be happy to assist you with the "B8532646" 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. Download and install the firmware for Win 10 (64-bit) from this link.  

Hope this helps! Keep me posted.
