    Hi sir:
    Hope you are well with Covid-19
    you must see if you machine has console control(ergonotronic).

    2) If have depend of serial machine has : 1) drive motor for inking roller or 2) mechanicaal.

    3) if is controled by mechanical, you must see if some parts has worn, or lack of LUBE, or disajustment in the system of roller.

    4) of course you must see if the power supply for control of ink roller has working good in the console control, since this control the PLC, because normally this press has PLC, and you must test if the output of PLC is arriving to the Motor driven in the unit(s) look for your schematic diagram.

    5) the coupling unit ink rooler has Pneumatic system-electrical in some cases, look for leaking in the system , or faulty electro valve .

    Let me know.

    Blessing

    Thank you Sir for the reply and steps.
    Our press is 2001 KBA 162a
    The rollers drop sometimes and other times not, but is still ducting ink rollers.
    The ink rollers should come on automatic when in impression
    We have checked for roller settings, air leaks, worn parts etc

    Can you please send pictures and solutions that we can apply?

    Thank you and Stay Safe
    Blessings
