    Try the LVPS. Can you get far enough to get any codes?

      Could be the flash cards. Either try updating firmware through the back-door (turn copier off, turn back on while holding utility key down, press trouble reset, then go straight into tech mode.) Also can try leaving the copier off over night and let all the capacitors discharge and then try in the morning. Don't laugh - has worked on a few occasions.

        Bizhub 750 Please Wait

        Look in the Errorcodelist, (Tech Rep Mode) There may be some dirt on the Gamma Sensor. Good Luck
