Hamada e47s impression problem

Hi everyone
I have a hamada E47S that was running great untill this morning the impression is not turning on. The sheets just comes out blank in the delivery table.
Can anyone please help me on how to go about troubleshooting the problem

N.B. there is no hamada technician in Trinidad and i don't have the wiring diagram.

Thank you
Regards

Check your impression linkage not to familiar with your press but I'm guessing it's on the no op side

 

the impression is turned on by a solonoid on the op side
there is a paper detection sensor right before where the paper enter the cyclinder grippers

 

A wiring diagram would give you a head start , but my guess is start by checking the magnet on the op side, if its engaging and đis engaging.

 

Thanks to you guys.......the problem was a short in the connection close to the sensor
Thanks again
