Ignore the first response, that is likely a scammer as the link is not to any site you would want to go.
the 50.2 error is a slow heat error, meaning the fuser takes too long to reach temperature.
50.4 is a fuser drive circuit error.
So it could be as simple as your available electrical supply is bad and not providing enough current. This error can be tripped by trying to connect a printer to a UPS or surge bar or simply an overloaded circuit.
The second error suggests a problem with the DC controller board or main power supply.
