Code 12 SM 74

Hey guys. I am having error code 12 pop up on the press and it shuts down. The code is for delivery but the area is clean. Any ideas?

 

Need pix of the error #12

 

hello dear sir, surely when you are working the sheets or something just touches a reception security. please watch the desktop screen while you are working you will see the default thank you very much!

 

Hello sir
make sure that all the security grilles are closed and there is no bad contact due to vibration, also the sheet overrun switch, since the problem is random, it is difficult to speculate, but the best way is monitored the reception menu at the time of production and as soon as the problem appears you can detect the source of the problem
