Fuser error codes for the Color LaserJet 3000, 3600, 3800, 2700, CP3505 series printers.
A 50.9 fuser error is one of the most common errors. If you get a 50.x error, you can try turning the power off and on and reseating the fuser but in almost all cases you will need to replace the fuser.
50.1 Low fuser temperature
50.2 Fuser warm-up error *
50.3 High fuser temperature
50.4 Faulty fuser
50.7 Fuser pressure release mechanism failure
50.8 Low fuser temperature (sub-thermistor)
50.9 High fuser temperature (sub-thermistor), or pressure release mechanism problem
* If you receive a 50.2 error, especially on the CP3505, and it only occurs when printing envelopes, try updating your firmware. Otherwise you'll need to replace the fuser.
