• A standard FRR system with separation and feed belt [A] and separation roller [C] comprises the original feed mechanism.
  • When the original picked up by the pickup roller [B] is fed between the feed belt and separation roller [C], if there is more than one sheet between the belt and roller, the separation roller will reverse feed and the sheets below the top sheet will be returned to the original tray..
  • The thickness of the double-feed triggers creates a small torque that exceeds that of the torque limiter clutch of the separation roller, the clutch reverses the rotation of the separation roller briefly (to send the double fed sheets back to the tray), and then releases so the top sheet can continue to feed.
