Hello everyone. Would be great if someone could help with Ink knifes problems. So this situation for me is first Time. When you are regulating from console the One knife, for example, the 13 knife, when the 13 knife is almost on his position then for some reason starts to light UP and gives the error on 11 knife. Then when you are regulating 11 knife, un some seconds machine gives error on 9 knife. Very interesting. Could someone give me suggestions. Its impossible to calibrate the knifes when they are living their own Life. Alredy i tried to change the motors, the potenciometres, calibrated all unit knifes how its said in the service manual. And nothing is helping really. Maybe its something to do with electric board or Power supply unit for the Ink knifes???? Dont know for sure. Power supply unit will put on the photo for you.
 
Power supply unit maybe
