HP doesn’t really do a good job at any troubleshooting tips besides reseating the AC power cable on the back of the fuser and make sure the ECU is fully seated. If that doesn’t work, replace the fuser. I guess if you really wanted to could take a volt meter and test the AC voltage going out of the ECU, which should be around 120V AC. Also make sure the connectors on the heating element are fully seated. More than likely you will be needing to replace the fuser though so  below is the instructions on how to replace the fuser on the HP laserjet P3005, M3027, and, M3035 printers for the 50.1 fuser error.

Conclusion about the 50.1 fuser error in the HP laserjet P3005, M3025, and, M3027 Printers
Usually when I’ve seen this error on this machine it’s been after the fuser film has torn. Several parts in the model printers are very weak and poorly made. Majority of the time those parts wear out well before the unit has any real usage on it that might cause a 50.1 fuser error. But as always the fuser is one of the most used parts in the machine thus resulting in the most errors. If you see the 50.1 fuser error on your HP P3005, M3035, and M3027 you probably will have to replace the fuser. After reading this article hopefully you will be able to get your machine back up in running if you experience this error.
