    The BICU is the only things these two codes have in common. I have seen 321s caused by a bad print controller.

        SC321 is a laser F-gate error.
        On older Ricohs I believe the F-gate signal went through the printer controllers. I seem to recall that a loose connection on the printer controller could cause SC321.
        Or faulty printer IO board.
