Abstract: An automatic retractor system for retracting a finger element extending from a transport belt, as for example, in a document set compiler and eject apparatus, including a belt transport system having ejector fingers extending therefrom for assisting in the transport of the document set from a compiler tray to an output tray. In particular, the automatic retractor includes a restraint arm coupled between the transport belt and the free end of the eject finger for pulling back on the finger as the belt travels over the circumference of a roll member defining the path of travel of the transport belt.
