    Kyocera TA3500I error 7401

    Have a Kyocera TA3500I that runs perfectly for a day or two with a brand new developer unit and then faults out with a 7401 error.
    Same machine also had to jockey the new drum unit when trying to install it. Checked connectors and contacts for proper connection and continuity and everything seems fine. Need suggestions.

    Is the machine clean? Ducts etc. ID sensor OK? Calibrations?
    Firmware up to date?
