Have a BH-C-284e in the workshop popping error code C4101, Polygon Motor rotation trouble. Machine was working but since it came in extremely dirty I dared to clean the PH-Unit as I did before by many of our older C-280's without any problem.
Of course am I the culprit by pulling the connectors and removing the unit, but could there be any other suspected parts besides the obvious connectors, Front side board, Printer control board or even the PH unit itself?
The machine has a "SB" label attached meaning a 1-Beam PH unit. A have eventually a loaner for parts but that's from a non "SB" label machine equipped with a 2-Beam PH unit and I doubt these can be used for testing.
Reconnecting all connectors didn't do anything yet.
