Sorm Feedig Problems

The feeder is properly adjusted and works fine. But when paper passes to Impression the machine feeds the first paper and stops.
The Impression was tested by putting a piece of paper on top of the photocell, it grabs it and cylinder impression is working .

So the feeding and impression don't work together. Is it caused by the sensor that is underneath the feeding table? Any other tests to do?

 

Can any one provide the parts manual? Still Can't name the sensor with the rotating cam underneath the feeding table

 

Did you cover only one reflex sensor? Your question can be better answered if you let us know which type of electronic barrier your machine is equipped with, WEKO or Teledix. The flag switch under the feed board dictates reading time of the eyes, if that is what you are questioning. Your machine sounds like it's detecting an early sheet.
