ABSTRACT:
A dual path sheet feeder is disclosed including a bypass transport loop and a main transport loop for selectively delivering sheets from a sheet feeding module to either a printer processing module or to a finishing module, wherein a movable gate situated adjacent to the bypass transport loop is provided for directing sheets along a predetermined path of travel. The movable gate is selectively positionable between a first position for directing the sheets through the main transport loop to the processing module to produce copy sheets prior to delivering the copy sheets to the finishing module and a second position for directing the sheets through the bypass transport loop to deliver insert sheets directly to the finishing module, circumventing the processing module. The dual path sheet feeder is contemplated for use in conjunction with a high speed electrostatographic printing machine for providing flexible paper supply options without the additional burden of providing supplemental dedicated sheet feeding trays.
