 Service Manual Tips

1. Reconnect the connector J128 between the fuser and the DC controller PCA.

2. Turn the machine off, reseat the fuser. Replace if the problem continues.

3. Replace the low voltage power supply if replacing the fusing assembly fails to fix the problem.

Personal Tips

1. As these machines age sometime the fuser fails to get to the correct temp. Also, every once in awhile you might get this error turning a quick power outage. Turning the machine off then back on might fix the problem. My theory is once in a great while is OK. Twice in a month or two and time to replace the fuser.

2. Check the power source. Make sure the machine is plugged into a wall outlet and not a battery backup, power strip, or other large devices on the same circuit.

3. Remove the fuser and check the connectors on either side of the heating element. I’ve seen the clips break or not get seated properly. This can lead to odd or intermittent fuser errors.
