    Mr mozdahir, please make this diagnosis:

    First of all, make sure that the communication cable is properly wired (pink cable) on the SCU side and on the IDCB card side of the inking motor control in the inkwell.

    Check the presence of the DC24 voltage for controlling the IDCB in plug X11

    Ensure voltages +5 v, +15 v, -15v in the switching power supply on the IDCB

    Give me the state of the leds that you will find on the IDCB (led H3 on the left next to the X15 communication card and H1, H2 in the middle of the card.

    Please leave me photos of the condition of the LEDs.

    Hi my friends, we live the same problem on SM74-8 color.

    How you fix your problem? is it software or cable problem?

    Hi sir .

    Check the presence of the DC24 voltage for controlling the IDCB in plug X11

    Ensure voltages +5 v, +15 v, -15v in the switching power supply on the IDCB.

    Good luck
