42. A document processing device, comprising: an input receptacle configured to receive a plurality of stacks, each stack including a batch of documents and a separator card associated with the batch of documents; one or more sensors disposed along a transport path, at least one of the one or more sensors configured to detect characteristic information associated with a document and generate a signal indicative of whether a particular document meets or fails to meet at least one criterion, at least one of the one or more sensors configured to detect a separator card; a transport mechanism configured to transport the batches of documents, one document at a time, and the associated separator cards from the input receptacle along the transport path; at least one output receptacle; at least one first offsort receptacle; at least one second offsort receptacle; and a controller configured to cause the transport mechanism to transport each document that fails to meet the at least one criterion to the at least one output receptacle, the controller further configured to cause the transport mechanism to transport each document that meets the at least one criterion to the at least one first offsort receptacle, the controller further configured to cause the transport mechanism to transport a separator card to the at least one first offsort receptacle if at least one document in a batch of documents associated with the separator card meets the at least one criterion, the controller further configured to cause the transport mechanism to transport a separator card to the at least one second offsort receptacle if all documents in a batch of documents associated with the separator card fail to meet the at least one criterion.
