Printer 5740 with C4EB82C3 error code

Hi @CaptBen


Welcome to the HP Support Community. I'd be happy to assist you with the C4EB82C3 error. 


Let's try these steps -


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 update from this link for Win 10 (64-bit). 


Hope this helps! Keep me posted.
