I had to replace the dim on the controller for 672

I'm having same issue the only thing I haven't t ried is op-panel and harnesses. I found part number for op-panel and usb harness but not the grey wiring harness that goes to BICU. I scoured the parts manual. did any of you order both harnesses? if so do you know the numbers? Thanks

Harness part numbers are on the point to point circuit diagram but I doubt very much if that is the problem. My experience is it that if you have unplugged the HDD and the fax and it still has the problem you are looking at a new ops panel or controller.

The harness parts numbers are on the point to point diagram. Ok

I have had a bucket load of these and the issue has been the main drive motor shorting out the controller.

Imprestik have you had any do this recently?

I agree with a few people on here, that it could be the Fax board. I have only had one that required a new controller. A couple of times it was just the little MBU board that resides on the fax board, it "un-seats" a little bit (only held down by the connector and two plastic "posts"), and can cause that code. Something to check anyway.

Remove Fax bored

Try setting in SP Mode System - 5191 to 0. It's worked for me couple of times regarding SC672 issues.

[TonerMunkeh]

These things don't have that SP mode

I had this the other day. Removed fax and code went away! Went back replace Fax board and all is well.
