The original problem was sc554. The fuser belt was shredded off. I replaced the fuser with a new one with the reset fuse in it.Did sp5810-2 The sc554 did not reset. There was a bulletin to follow for this code. I checked the heat data and all but one were good so I replaced the io board and bicu. This cleared the sc544 but now I am getting a sc547-02. Which is 0 cross reference problem. I replaced the power supply and the ac driver board but no luck. I checked all connections and did not see anything off or pinched. Getting desperate I also replaced controller and ipu boards. I noticed on the controller board I replaced has had the cable ripped out of it because the connector was bent up. I left the new control board in it. Any ideas on the sc547-02 Tech support thinks its a pinched wire or something but I sure can not find it. I did check the new fuser on another copier and it works fine. I asked tech support about the thermal sensors behind the fuser and they did not think that would cause the code to pop up. Thanks for any input.
