    No need to worry just use translator and right technical knowledge.

    it was nice and solid ^^ after 100 full coverage prints - look 2nd image. In normal printing mode, about 5k will be printed before the density drops and another 3-5k to c2802
    1. I'm also leaning towards to TCB or TCRS. waiting for parts
    2. the toner is delivered in small portions only during printing. I don't know if this is normal

    Then to wait and see if the TCB and TCRS makes the difference. Keep us posted.

    In normal operation the motor on the sub hopper pulses continuously. Short rotations.
    Whatever

    Re: Konica pro 1100 c-2802 low density

    Ok got this advise form a big KM importer. Have not tried this myself but will have a go at it when i am faced with the C2802 and C2803 error codes.
    Said that this works. Difficult to except the solution.

    Remove the frosted lens from the IDCS exposing transmitter and receiver part of the sensor.
    If you do this please let me know is that makes a difference.

    Don't discard the developer just tone it up and initialize it again.

    Also if you do the particularity > gama auto adjust check the error it gives there and check the meaning in the service manual.

    Under Service mode > Machine Adjust > IDC Sensor adjustment should be done in the case of poor density or sensor replacement.

    Do you mean a protective film or a light grey film covering the sensor itself? I thought about it and I just never did it.

    Yes the plastic layer covering the sensor.

    I did it. Now error c-2803 Well then there really were no problems with spot detection
    This is the way...(c)

    So you think the IDC sensor is working ok?
    Did you get the replacement IDCS?
    What error do you get if you run auto gama adjust?
    Whatever
