A multibin, cut-sheet xerographic copier capable of operating in a simplex or a duplex copy mode, wherein sheets are fed from a selected sheet stack, one at a time, to the copier's transfer station, by a sheet feeding means which includes a combing wheel. The combing wheel shingles the leading edge of the stack's top sheet to an open feed roller nip, to be sensed thereat by a pneumatic sensor. Sensing of this leading edge causes the combing wheel to be lifted off the stack. Subsequently, at a time determined by the copier's control logic, the drive nip closes to thereby feed the top sheet to the copier's paper registration gate, and then to its transfer station. As soon as this sheet's trailing edge has cleared the pneumatic sensor, and the drive nip has opened, the next sheet is staged at the shingled position, in the open drive nip. Means are provided to deshingle the stack when the copier's paper supply drawer is opened, as for reloading paper. The combing wheel, drive nip and associated assemblies are supported by a single frame member, and are thus removable as a unit for replacement or repair.
A sheet fed xerographic device having means operable to control the xerographic process, including the serial feeding of sheets to a transfer station, comprising:
A sheet fed xerographic device capable of selectively operating in a simplex or a duplex copy mode, having a first and second paper supply drawer, each of which is movable from an operative position to an inoperative position whereat the drawer is operator-available for paper stack reloading;
In a cut sheet fed printing device having logic control means operable to control the printing process, including the serial feeding of sheets to a station, the improvement comprising:
A cut sheet fed printing device having means operable to serially feed sheets to a station, comprising:
A cut-sheet fed electrophotographic device having control means operable to control the electrographic process, including the serial feeding of copy paper sheets to an image-receiving station, comprising:
A cut-sheet fed electrophotographic device having means operable to serially feed copy paper sheets to an image-receiving station, comprising:
A sheet fed xerographic device capable of selectively operating in a simplex or a duplex copy mode, having at least one paper supply drawer and a duplex bin wherein side-one copied sheets are stored prior to side-two copying, and having logic control means operable to control the xerographic process, including the serial feeding of sheets from said paper supply drawer or said duplex bin to a transfer station, said duplex bin comprising:
