Paper feeder for a single sheet printer

A method of equipping a single-sheet printer with multiple paper feeders, the method comprising the steps of:

• providing a first paper output device having a plurality of paper compartments and a first conveying path, the plurality of paper compartments including a drive mechanism for delivering a sheet of paper to the first conveying path, the first conveying path being constructed to convey the sheet of paper to the single sheet printer, the conveying path being connected to a first branching portion, the first branching portion being connected to a first paper acceptance station,
• providing a second paper output device at the first paper acceptance station, the second paper output device including a plurality of paper compartments, the plurality of paper compartments of the second paper output device having a drive mechanism for delivering a sheet of paper to the first paper acceptance station, the second paper output device further including a module conveying path constructed to receive the paper sheet from the paper compartment of the second paper output device, the module conveying path being connected to a paper sheet delivery station that is connected to the first paper acceptance station,
• connecting the first conveying path of the first paper output device to the printer, and
• connecting the module conveying path of the second paper output device to the first paper acceptance station of the first paper output device.
