Abstract:
In a sheet feeding and separating system for feeding separated sheets downstream from a stack of sheets in a sheet stacking tray having a sheet stack supporting surface, wherein said sheet separating system includes an active sheet retard system downstream of said sheet stacking tray with a sheet kickback system for kicking an unseparated sheet back upstream towards said sheet stacking tray, the improvement comprising:a sheet kickback control system comprising a high friction surface member mounted in said sheet stacking traysaid high friction surface member extending vertically substantially above said sheet stack supporting surface,said high friction surface member being positioned upstream of said sheet feeding and separating system to underlie the upstream end of said stack of sheets in said sheet stacking tray and to frictionally engage and retard upstream movement of the bottom sheet of said stack of sheets by said sheet kickback system and wherein said high friction surface member comprises a high friction elastomer material such as EPDM.
