Hi @SO62WEO,

Welcome to The HP Support Community.  

Thank you for posting your query, I will be glad to help you.

I understand you are getting the error code B80B746C on HP printers generally points to a hardware-related issue. Flashing lights and the inability to power off can indicate a deeper problem that may need a manual reset or service. 

Here’s what you can try:

Hard Reset the Printer:

• Disconnect the printer's power cable from the wall outlet (leave it connected to the printer).
• Wait for about 60 seconds.
• Press and hold the Power button on the printer for around 15 seconds to discharge any residual charge.
• Reconnect the printer to the power outlet and try to turn it back on.

Firmware Update (if accessible): Update the firmware on an HP printer

• If you manage to get the printer operational again, update the firmware. Firmware updates can address specific error codes and improve printer stability.
• You can check for updates through the HP Smart app or HP Support website under your printer’s model.

Check for Physical Obstructions:

• Open any accessible doors and compartments and check for any jammed paper or loose components that might be triggering the error.
