Repair of the 50.2 Fuser Error on the HP P4014, P4015, P4510 and P4515

Diagnostic Aids for the 50.2 Fuser Error in the HP P4014, P4015, and P4510

In these machines the 50.2 fuser error is caused by a fuser warm up service problem inside the machine. Lots of things can cause this problem so in this article I’d like to talk about a few of them to hopefully walk you through the situation and decide if you need to purchase a replacement fuser or not.

1. Power Cycle the product to see if the error is persistent. If it continues then turn the machine off unplug it from the power source and let it sit 20 to 30 minutes and try again.

2. While your waiting for the machine to cool down and the capacitors to discharge check the power source. For testing purposes make sure you have it plugged straight into a wall outlet. HP recommends not having these plugged into power strips with other devices that consume lots of power like coffee makers, space heaters, and other laser printers or copiers. Also never plug these printers into a battery backup or UPS. In all these situations you can run into a power struggle issue where your equipment might not be getting enough power resulting in warm up issues and the 50.2 fuser error.

3. Remove the fusing assembly from the back of the printer and visibly inspect the unit. Verify the fuser film is still in good shape, check the connectors to make sure they are fully seated then reinstall the unit back into the machine listening for it to click in place.

4. If all the above steps have failed to clear the 50.2 fuser error from your machine then it’s time to replace the fusing assembly. Below is a link to purchase a new fusing assembly and also a link for instructions on how to replace the fusing assembly when you get your replacement part in.
