Patent ID: 7307741

Claim:
A method of automatically on-line inserting pre-printed special insertion sheets into desired page locations of pre-collated plural page printed documents while they are being printed and outputted by a printer, wherein the printer has plural sheet feeding trays for feeding blank print media to be printed by said printer from one side of said sheet feeding trays to the print engine of the printer, wherein pre-printed special insertion sheets are loaded into at least one of said sheet feeding trays and selectively fed to be outputted by the printer inserted at desired interposition page locations of said plural page printed documents being printed and outputted by the printer from said blank print media, wherein said pre-printed special insertion sheets loaded into said at least one of said sheet feeding trays are fed out from the opposite side of said sheet feeding tray, opposite from said feeding side of said blank print media, and wherein said pre-printed special insertion sheets are fed from said sheet feeding tray in a different sheet feeding path which substantially bypasses said print engine of said printer and outputs from said printer sequentially integrated into said pre-collated plural page printed documents without requiring a separate sheet inverter module; wherein said at least one sheet feeding tray is disposed generally below the print engine of the printer, and the print engine accepts sheets to be printed on an input side thereof; and wherein said printer has a sheet inverter with an inversion chute on an output side opposite the input side thereof, and wherein said pre-printed special insertion sheets being fed in said different sheet feeding path from said opposite side of said at least one sheet feeding tray to said printer output are fed through said inversion chute.
