    MFPB or Laser is my wild guess, but re-connecting MFPB and HV Board my be cheaper way start to eliminate connection issues.

    But something tells me this has been here once on CTN ..Isn't it the Drum drive issue with the encoder in the drive unit?
    .OK Google! ... will I need Berrocca this morning?
