Claim One:
1. In a document handling and digital imaging system for sequentially feeding plural document sheets in a document feeding path from a document input to an electronic imaging station to be digitally electronically imaged in electronic pixels as document page images and fed out from said electronic imaging station after said electronic imaging, with a system for detecting document sheet feeding stoppages in said document feeding path, the improvement comprising a simplified job recovery system including: a system for generating and storing electronic indicia indicative of said digital electronic page images of said documents which have been fed in said document feeding path to said electronic imaging station and electronically imaged; an operator display instructing the operator in response to a said detected sheet feeding stoppage in said document feeding path to remove document sheets from said document feeding path and reload said removed document sheets into said document input even if said removed document sheets have been electronically imaged, for refeeding said removed document sheets in said document feeding path from said document input to said electronic imaging station to be electronically imaged; said system for generating and storing electronic indicia indicative of said digital document page images further electronically generating and storing subsequent electronic indicia indicative of said subsequent digital electronic page images of said removed documents which have been refed in said document feeding path to said electronic imaging station; and a duplicate electronic document image detection system electronically connecting with said system for generating and storing electronic indicia indicative of said digital electronic images for automatically comparing previously stored electronic indicia indicative of said previous digital electronic images of said documents prior to said detected sheet feeding stoppage with said subsequent digital electronic images of said removed documents which have been refed in said document feeding path to said electronic imaging station, to detect duplicate digital electronic images and to provide a duplicate electronic images signal for the automatic deletion of duplicate electronic document page images.
