Troubleshooting The HP LaserJet 50.1 Fuser Error


First thing to try in troubleshooting the HP laserjet 4300 50.1  fuser error message is just turning off and on the machine. Second, check and make sure the power cable is directly plugged into a wall socket. These machines draw a lot of power so they should never be plugged into a power strip with other devices, battery back up, and make sure there are no other large equipment or heater type products on the same circuit. Heater devices include: coffe makers, copiers, laser or solid ink printers, and space heaters.  Third could just be the age of the unit. Over time the heating element gets worn and it takes longer to warm up thus resulting in a  50.1 fuser error. Finally turn the machine off and unplug it. Let it set for 10 to 20 minutes then plug back in.

Conclusion About the HP LaserJet  4300 50.1 Fuser Error

The DC controller or power supply can also result in 50.1 fuser errors but it’s very uncommon. I’ve worked on hundreds if not more 4000 series machines and have only run into one 4100 printer that needed the power supply replace to fix a fuser problem. I’ll say if the above tips didn’t solve your plem 99% of the time replacing the fuser will fix it. Hopefully this article has helped you discover the root of your 50.1 fuser error on your HP laserjet 4300 printer and you were able to get your machine back up in running in as little time as possible.

HP 4300 Laserjet Fuser Removal

Note: Unplug power and communication cables and allow at least 10 minutes for cool down before fuser removal.
1. Open the rear output bin. Use your finger to squeeze the hinge pin (formatter side) out of its mounting hole.
2. Rotate the output bin away from the printer until the right hinge pin is released, and then remove the output bin.
3. Squeeze the blue fuser release tabs
4. Pull the fuser straight back and out of the printer.
