    hi the last time i saw this code it was to do with a compatible toner fitted to the mc, which toner was the last one put in or take out all toners to see if it runs up or it could be drum problem.

      E751-9000/
      24V down was detected during communication with the drum unit or toner container. (The color cannot be
      identified.)
      Check the power supply output of 24V series on the main power supply PCB.
