50.1 fuser error – HP Color Laserjet 3000, 3600, 3800, and CP3505

Probably the most common fuser issue that arises on any HP color laserjet 3000, 3600, 3800, and CP3505 printer is the 50.1 fuser error. The error is a result of the machine reading a low fuser temperature. Several things can happen to result in a 50.1 fuser error. First thing to check is the power source. Call HP or any other service and repair provider and they will recommend that you plug the machine straight into a wall outlet and to avoid power strips, surge arrest, and battery back ups. These machines use a lot of power. Plugging them into power strips with other devices can draw the voltage down throughout the circuit. While it might not affect other devices these machines have thermistors in them that measure the temperature of the fuser. If the temperature falls out of range the machine will throw you a 50.1 fuser error code. Second thing to check is the fuser itself. The fuser is easy to remove and replace so pull the fuser out and reseat it to verify that it’s properly seated. Third thing to try is just turning the machine off and back on to see if it comes up to its proper temperature. Sudden power outages are known to cause odd problems like this. Finally, turn the machine off and unplug it for 10 to 20 minutes. This allows the HP color laserjet 3000, 3600, 3800, and CP3505 to reach a cold state. This can clear out any error codes stuck in the machines memory and let it go through its normal start-up mode if it previously wasn’t.

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.

  1. This post on the 50.1 fuser error was exactly what was needed to diagnose the problem of a cold dead fuser. Unfortunately the reference to a source for a new fuser was not included in the article. Can you provide that? Also where can a new correct DC controller PCA be found? Also, is the DC controller firmware found on the HP website? Many thanks

  2. Sorry David, Amazon is suppose to let me know when the links no longer work. Thanks for letting me know. Anyway its fixed now. The DC controller firmware can be found on HP’s site under drivers and software just enter which machine you have and it will take you to the right area. The DC controller I’m not really going to worry about. Maybe 1 out of 200 will need the DC controller. Chances are slim to none
