ABSTRACT:
A duplex recirculating document sheet feeder jam recovery procedure starts with removing the copy sheets from the document sheet path and facially orienting the removed sheets the same as the top sheet in the hopper. The removed and oriented sheets are returned to the top of the set in the hopper in the sequential order starting with the furthest downstream sheet along the document sheet path, and progressing sequentially toward the hopper exit. The document sheets are then fed seriatim from the bottom of the hopper, through the document sheet path, and back to the top of the hopper in their initial facial orientation if the last set of a job is in progress, and otherwise in the facial orientation opposite to their initial facial orientation. Again, the document sheets are fed seriatim from the bottom of the hopper, through the document sheet path, and back to the top of the hopper until as much of the document set as has already been copied in the current run has been returned to the hopper. Copying may then be resumed.
