I have encountered the same problem. What I did first was I swapped the whole operation panel to check if it is good or not.I found out that there was nothing wrong in the operation panel.

I have rectified the problem by replacing the BICU board and the polygon motor at the same time.Proven and tested!

By replacing the BICU sometimes you an fixed the m/c temporarily . The real cause of the problem is the damaged duplex harness which are grounded and damage the BICU.
