Color LaserJet 3800n 50.8 Fuser Error

I've tried resetting the printer, also removing and redocking the fuser. Everything looks to be in good shape.

When the printer turns on the fuser makes two clicking noises. Not sure if thats working as intended.

Please if anyone has any further troubleshooting I can do, let me know.

Re: Color LaserJet 3800n 50.8 Fuser Error

50.8 Error:
1. Verify the fuser is installed correctly
and fully seated.
2. Check that connector J6007 on the
fuser is seated correctly. Replace the
connector as necessary.
3. Turn off the printer.
4. Remove the fuser.
5. If there is no conduction in the
subthermistor, 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. Upgrade the DC controller firmware.
8. Replace the DC controller PCA.

The 2 clicking sounds are totally normal. The 50.8 error indicates that the fuser is bad.

Re: Color LaserJet 3800n 50.8 Fuser Error

After trying all the troubleshooting techniques I could find on the web. I simply just replaced it with a new fuser.

Cost was $190 for a brand new one, and $139 for a refurbished exchange.

I purchased the new one, it just arrived today, and the printer is working seamlessly.

Thank you for replies.
