    I have a problem with my machine, the lateral and circomferential register does not work well, the two have rotated and are going remains stuck that of the 1 group and 2 group. when you turn it by hand with the key 17, it turns without worry but when we press on the desk, it turns and goes this stuck. for that of the circomferential one unstuck it and it turns in a single without and will stay stuck but for action at the desk while the machine is running it does not turn. even after having interchanged the MOT 3 cards, the problem still remains in group 1 and 2. even having inverted the MWE the result does not change. I have my MWE card which heats that of the 1 and 2 group. Thank you for help

    the problem takes place on the first head and the second head. the third and fourth head have no problem. after research I discovered a card which has a burnt component and I repaired it. when I have it back up and I turned the machine on, I saw a vapor coming out of the compound change but no burn but the problem still remains and one of the MWE boards is heating up. Thank you for your help.

    The motor commutator and brush may not have good contact because of oil and carbon dust. cleaning it will solve most of the time.

    Hi
    Normally mwe/mot burnt due to short circuit (in cable, potentiometer, sprial cable on the operator side.
    You have to check following
    1) P1, P2 unit check circumferential, lateral motor potentiometer, 1st .
    2) check cable for any damage/short from connection board in cpc/cp2000
    3) check chekc motor for oil (drive side motor normally get full of oil) due to which it take too much load in million second that card can burnt.
