I have Fuser Error 50.2 (sometimes 50.4). I have replaced the fuser with a new HP part. Same issue. I have reset back to factory settings. Cycled power. Same alarm.

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. 

If you find the information provided useful or solves your problems, help other users find the solution easier by giving kudos and marking my post as an accepted solution.
