Tips on Repairing the 50.1 Fuser Error on the HP Color LaserJet 2700 Printer
I mainly see the 50.9 or 50.1 Fuser Error on these machines. The 50.1 fuser error repair means the fusing assembly is experiencing a low temperature reading. In this article I’d like to talk about this error and give some advice on resolving the problem.
Repair Tips for the HP Color LaserJet 2700 Fusing Assembly – RM1-2665
1. Turn the printer off and back on. A lot of times when the fuser is on its way out simply turning the machine off then on again will get it going for a while longer.
2. Check and make sure it’s not plugged into a power strip with multiple devices and or a battery back up. In these scenarios power is being drawn away from the machine to other devices and can cause this issue. HP recommends that they be plugged straight into a wall outlet.
3. Check the Error log. If you see this error happening more than once in the past month or so then the fuser is starting to go out and needs to be replaced.
4. Reseat the fusing assembly
5. Replace the fusing assembly
Service Manual Tips for the 50.1 Fuser Error Repair
1. Verify the fuser is installed correctly and fully seated.
2. Check that connector J6007 on the fuser is seated correctly.
3. Turn off the printer.
4. Remove the fuser.
5. If there is no conduction in the main thermistor, measure the resistance between fuser connectors J6007LA-1 and J6007LA-3. If the resistance is not 100 kohms to 3 Mohms, replace the fuser.
6. If there is no conduction in the fuser heater, measure the resistance between fuser connectors J6007LAF-1 and J6007-2. If the resistance is not 5 ohms to 1 kohms (100 to 127 V) or 20 ohms to 1 kohms (220 to 240 V), replace the fuser.
7. Replace the DC controller PCA.
