After changing the main board you'll get the C0180 code. Go into MM004 to clear the 0180 code.

After replacing Main Board we still have the issue. Back to the drawing board.
Retracing all of my steps, I believe the issue started after performing U002 (resetting factory default data). I have used this mode on other models and have not had any issues. I'm wondering if it lost rom data from the factory and has no reference point for toner?
It will do the toner initial adding if you performed U002. You will have to wait for it to finish. There is one more thing to be checked in this case. That's the developer drive gear which breaks every now and then:
