50.8 Fuser Error In the HP Laserjet P3015 Printer

 

50.8 Fuser Error – Thermistor 2 Reading a Low Temperature State

The 50.8 fuser error in the HP laserjet  P3015  means the thermistor  2 in the fusing assembly is reading a low temperature state. As the machine warms up the thermistors are reading the temperature inside the fuser. After a set amount of time if the thermistors still don’t read the correct operating temperature then the machine errors out and  waits for user intervention to prevent further damage. While this error is not as common as some of the other fuser errors, it still hopefully can be fixed with out replacement of the fusing assembly, RM1-6274-000CN. In this article I’ll discuss a few of the tips that can help you troubleshoot   the error condition, give you input on what the service manual has to say in regards to the error and give directions on how to replace the fuser unit if needed.

Troubleshooting tips for the 50.8 Fuser Error HP P3015 fuser error photo

First thing to try is to just turn the machine off and back on. Sometimes sudden power outages like when the lights flicker can cause 50.8 fuser errors because the machine can try to read the fuser temp at the wrong time. Second thing to take a look at is the power source. Anymore manufactures recommend machines be plugged straight into a wall outlet. Battery backups are a huge no no as the printers draw to much power from the back up resulting in shorter battery life and possible damage to the power supply inside the printer. Power strips are bad because of the fact that having too many devices on the same circuit can draw down the amps and voltage on the line resulting in low temperature states in the fuser because not enough power is being supplied to the unit. Third thing to try is to turn the machine off and unplug it from the wall. Waiting 30 minutes then plug back in and power up. This allows the capacitors on the boards to fully discharge which can clear out any error messages stuck in the memory. Also it allows the fuser and other components to cool down so when the machine restarts it has a better chance of getting to the correct operating temperature. The fourth and final step is to read what the service manual says below or try and reseat the fusing assembly.
