    Check the black development gears - they're probably not rotating properly, and so the machine keeps trying to add toner.

    This. Had many dev units fail on these. Dev unit seized up and your toner supply auger in the hopper is tangled and or snapped off now too.

    The coils in the developer unit are very fragile and can easily break when faced little resistance. This can happen within normal operation of machine. Unlike the MP c3003+ models it's not driven by a motor so toner is not always mixed properly which can result in hardened toner causing it to break.

    Refer to this thread as well

    RICOH MPC2003 Black toner empty signal.
    If it works, don't touch it.

    Usual fix is to fit a new Dev assy and toner supply unit.

    Check toner hopper for hardened toner inside... Can cause this problem

    Once the dev unit fails toner backs up & breaks the toner hopper.

    I always replace a dev unit with a new hopper as a set.
