50.2 Fuser Error Warm Up Issue
So far the HP Laserjet  P3015  printers has been a nice relief from the constant problems the P3005  series printers had. I’ve seen several P3o15  machines have over 150,000 prints on them and the fuser  is still going strong. But like any other machine fuser errors will happen. In this article I’d like to go over the 50.2 fuser error on these machines. I’ll talk about why they can happen and several things you can try before replacing the fusing assembly. Obviously fusers aren’t the cheapest things in the world so it’s best to try a few things before just throwing in a part you might not need.
Troubleshooting Tips for the 50.2 Fuser  Error
The 50.2 fuser error on the HP laserjet  P3015 printer is a fuser warm up error. Several things can cause this error. First thing to try is just to turn the machine off and back on. Sometimes sudden power loss like a brown out or lights flickering can cause this problem. Next thing is to verify that it’s plugged straight into the wall and not a power strip or battery back up. Again, other devices can cause power related issues with these printers and 50.2 fuser errors. Third thing to try is to turn the machine off and unplug the printer from the wall outlet for 30 minutes. This allows the fusing unit to cool down and the capacitors inside the machine to loose their charge. This allows the machine to restart from a cold state when it powers back up. Any error codes stuck in memory should clear and the machine goes through a more thorough warm up state. If the error continues then you can try the steps below in the service manual. However, majority of the time replacing the fuser at this point is the recommended next step.
