I had this code come up on this machine near the end of last month. I put in a used fuser unit, and everything seemed to be working great until just this past Monday. Now I can't clear the code. I replaced the PCU PWB, made sure the thermistors on the replacement fuser were clean, and still can't get the code to go away. Firmware it up to date, connectors look good, no broken plastic around them or bent pins from what I can see. I'm wondering if the original PCU PWB took out the thermistors on the replacement fuser? I will be taking another used fuser over in the morning to test that theory, but I'm open to suggestions.

Checkout this post. It's for the next generation machine but it might help out
Good luck

So far, it seems that my theory might have been correct. I put in the used fuser this morning, powered up the machine, and the code was gone. All jobs that were waiting in the queue printed out and the code didn't return. I will be ordering a new fuser and keeping my fingers crossedComment
