    Bizhub C257i Fault Code C5351

    Have a Bizhub C257i showing fault C5351 and I think that points at the Power Supply cooling fan??
    Could anyone please give me a part number for this.

    Thanks.

      Can confirm. Not US market and cannot access Service Manual

      BUT

      for the c250i it does point towards the power supply cooling fan.

      Check connectors, then replace fan, then replace EXCB, then CPUB, then Baseboard.
      I had a few issues with the fans Konica used right before leaving, so its probably that.

        Can be found in many-many i-series machines.
