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.

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. Upgrade the DC controller firmware.

8. Replace the DC controller PCA.
