Definitions

  • recirculating document handler In the recirculating document handler (RDH) 20 here, individual original documents are sequentially fed from the bottom of a stack of documents (placed by the operator face-up in the document storage area or stacking tray 24) to the imaging station 26, which is the conventional platen of the copier 10, to be conventionally imaged onto a photoreceptor 12 for the making of copies in a conventional xerographic manner.
  • the document handler 20 has conventional switches such as 29 for sensing and counting the individual documents fed from the tray 24, i.e., counting the number of document sheets circulated.
  • a conventional resettable bail and its associated switch 31 indicates the completion of each circulation of the complete document set and then is automatically reset on the top of the stack before the next circulation.
  • Document page 3 is printed on its opposite face, and, due to the inherent inversion in the processor output path, this second copy sheet out is placed in the output path with its page 3 side face-up and its page 4 side face-down on top of the preceeding page 5 copy sheet.
  • the next even document page, page 2 is also copied on a clean copy sheet from tray 106 or 107 and fed into the duplex tray 116 on top of the preceeding page 4.
  • the last copy sheet in each set is fed from the duplex tray 116 and it receives the document page 1 image on the opposite side of the previous page 2 image and is likewise outputted.
  • the copier controller would change the copying sequence and not skip the first and subsequent alternate documents being recirculated in the first copying circulation. Rather, it would skip pages 3 and 1, the second and alternate documents, to copy only the even pages 2 and 4 in the first circulation.
  • the second copying circulation it would feed the first copy sheet (page 4) to the duplex tray, not to the output, since it is an even page to be duplexed, as described above.
  • the present system properly and consistently handles letterhead or other pre-printed or pre-punched copy sheet stock or forms for duplex copying for either an odd or even number of duplex, or an even number of simplex J originals.
  • page one the odd page
  • the binder holes must be on the left side of the odd pages.
  • these restricted copy sheets can desirably always be placed face-up in either of the copy sheet trays, yet will always be properly duplexed, since the proper even page sides are always printed on the back of the copy sheets first as they are fed from the copy trays, and then the odd document pages are copied onto the front sides of the copy sheets as they are fed from the duplex tray.
  • the two documents are re-circulated for copying, e.g., for 60 duplex copies of two documents with a 25 sheet capacity duplex tray, 25 copies are made in the first circulation, 25 in the second and ten in the third.
