    摘要： A method and apparatus of processing sheet media such as document sheets to be duplex scanned or media sheets on which two sided printing is to take place includes automatic positioning of an active sheet guide gate and drag clutch 70 by the rotation of a transport roller (50) with which the active gate and drag clutch is frictionally engaged. The transport roller may comprise one or more coaxial rollers (50) in an assembly positioned in the media path and is rotatable in different directions such that the leading edge of a moving media sheet is moved through one or the other of two nips defined between the transport roller assembly and associated upper and lower pinch rollers. The direction of rotation of the transport roller assembly can be reversed before the sheet leaves the nip to thus re-position the sheet guide gate and re-route the sheet back in a desired path to a scanner or printer for further sheet processing.

    摘要： A method and apparatus of processing sheet media such as document sheets to be duplex scanned or media sheets on which two sided printing is to take place involves the controlled rotation of a transport roller assembly (50) positioned in the media path in different directions such that moving media sheets engage a crenellated surface of the transport roller assembly which moves the leading edge of the moving sheet toward one or the other of two nips defined between the transport roller assembly and associated upper and lower pinch rollers (62, 64) or guides (27, 29). The crenellated surface of the transport roller assembly includes grooves (58) or spaces which extend in the direction of the leading edge of the sheet so that the leading edge of the sheet enters a moving groove to thus move the leading edge of the sheet in the desired direction. The direction of rotation of the transport roller assembly (50) can be reversed before the sheet leaves the nip to thus re-route the sheet back in a desired path for further sheet processing.
