ABSTRACT:
Method and apparatus are described for job recovery when jamming of copies occurs in copying devices generating duplex copies electrophotographically from either simplex or duplex originals. Recovery from jams while copying the first side of simplex or duplex originals can normally be immediately effected during the initial, or normal, run, after clearing the jam. Recovery from jams during copying of the second side is effected by clearing the jammed copies from the copying device, optionally inserting blank sheets as the initial copying run is continued to flag the position of each of the removed jammed copies in the generated stack of copies, rerunning the originals through the copying device after completion of the initial copying run with duplex copies being generated only as necessary to replace jammed copies occurring during the initial run, and then inserting the duplex copies last made in the proper positions in the stack of copies made during the initial run, which copies replace the blank flagging sheets, if utilized. The apparatus includes a plurality of counters, memory registers and comparators interconnected by logic circuitry to semi-automatically effect job recovery due to jammed copies occurring during duplex copying from either simplex or duplex originals.
