Welcome to HP Support Community.
Thank you for posting your query, I will be glad to help you.
The error code B80B746C on your HP printer indicates a serious issue, possibly related to hardware or firmware. Performing a factory reset might help, but given the symptoms you're describing, the printer may not respond to standard reset commands.
Here are some steps you can try to perform a reset, but please note that a complete factory reset may not be possible in this state:
Steps to Attempt a Reset:
Power Cycle the Printer:
- Unplug the printer from the power source.
- Wait for at least 60 seconds.
- Plug the printer back in and try turning it on.
Hard Reset:
- While the printer is off, press and hold the Power button.
- While holding the power button, plug the printer back into the outlet.
- Continue to hold the power button for about 15 seconds, then release it.
Factory Reset via Control Panel (if accessible):
- If the printer allows you to navigate the menu despite the error:
- Go to Settings> Printer Maintenance> Restore Factory Defaults.
I hope this helps.
Take care and have a good day.
