    Only thing left is the harness!

    I've attached the P2P for the harness part numbers from the IOB to to ozone fans.

    First off, SC584 does not exist for the Pro C751. In fact the only Production Color model it does exist for is the Pro C7110X. From Gooses Guide for the C7110X:
    Rear Box Ozone Exhaust Fan. PER README FILE Issue began after Engine firmware upgrade. Applying this firmware to machines not installed with the modified fans will cause SC584-00. For machines not installed with the modified fans, upgrade the System/Copy firmware to version 3.02, apply the following SP values, and then turn OFF/ON the machine.
    SP1-945-009 set to 100
    SP1-945-011 set to 100
    SP1-945-017 set to 100
    SP1-945-019 set to 100
    SP1-945-021 set to 100
    SP1-945-052 set to 0
    Now what is the actual Service Code you are getting?

    Second where the hell did you get the idea that performing a memory all clear was going to be helpful. Were you looking at a B/W service manual for SC584 which is a fusing error on B/W and mistakenly ran SP 5801-001 Memory All Clear instead of SP 5810 fusing unit reset. In any case if you did actually run SP 5801-001, Memory All Clear, you have created a whole new can of worms for you to have to deal with. Unless you have the birth certificate, you have created anywhere from 2 to 12 hours or more work getting the color back in alignment.
