Troubleshooting The Hp Laserjet 4200 50.2 Fuser Error

First thing to try is just turning off and on the machine. I replaced one last week that was giving a 50.2 fuser error every few weeks for a few months before they finally got sick of it and called me out to replace it.

Second, thing to check is were the power cable is plugged in. A lot of people don’t realize that the fusers heat up between 350 to 425 decrees. Essentially they are heaters that draw a lot of power. given the fact that they draw large amounts of power they should be plugged straight into a wall outlet and make sure no other heating device is plugged into the same outlet or circuit.

Third thing to check, if you just replaced it is if you were shipped the right fuser for the machine and voltage type. The 4240, 4250,4350, and M4345 fusers all look the same and fit into other machine but several of them are different and will not properly work. Also the 220v fuser fits in the machine but will not heat up properly giving poor print quality or errors like the fuser 50.2 fuser error.

Last thing to try is leaving the machine unplugged for 10 to 20 minutes and then plug back in and try again. If that fails then its time to replace the fuser.
