Switchable paper transport device for single sheets and continuous paper in printers

摘要

There is disclosed a paper transport device for printers. The device transports either single sheets or continuous paper through a printer in such a manner that switching between single sheet feed or continuous paper feed does not degrade print quality. When feeding single sheets, the platen determines the paper feed rate and is driven at a first circumferential speed. When feeding continuous paper, the platen is driven at a second and faster circumferential speed, which is slightly greater than the rate at which the paper tractor feeds the paper to the platen.
