HI everyone need help here please, I have IGT S 2000 multi nomination wild cherry , I tried to use key chip 17 to get printer to work , the machine said that the printer is enable but it did not work , I do see light and the printer does take the paper in , so the power is not the issue, then I read some of other issues in this section , and I notice the board for multi nomination needs key chip 45 , so I used the chip and the printer said it was enable , but it still does not work when I try to cash out and it says hand pay , what I am doing wrong / please any one ?
