摘要： A scanner assembly includes an automatic document feeder and a first scanner. The automatic document feeder defines a media pathway that includes an input portion and an output portion having an exit roller. The first scanner is positioned along the media pathway upstream from the exit roller. In a first assembled configuration, the assembly is configured to scan both a first side and a second side of the media via the first scanner. In a second assembled configuration, the assembly additionally includes a second scanner positioned along the output portion and interposed between the first scanner and the exit roller. In the second configuration, the assembly is configured to scan the first side of media via the first scanner and to scan the second side of media via the second scanner.

摘要： An automatic document feeder with a drive system that can efficiently handle double-side scanning and accommodate more than one timing sequence for sequentially picking individual sheets from a stack using only two motors—a pick motor and a media motor. The automatic document feeder includes a pickup unit with a pick roller, a set of de-skew rollers, a main media path configured to guide a media sheet from the pickup unit to a scanning region and from the scanning region to an output tray, and a switch-back path configured to guide the media sheet back into the main media path. The drive system is operable to provide a high-speed picking mode and a delayed picking mode. In the high-speed picking mode, the pickup unit is driven by the pick motor to pull a subsequent media sheet from a stack of media sheet as soon as a previously pulled media sheet has passed the pick roller. In the delayed picking mode, the de-skew rollers are driven by the pick motor to advance the media sheet toward the scanning region and the subsequent media sheet is pulled from the stack by the pickup unit when the previously pulled media sheet has passed the de-skewed rollers.

摘要： A sheet discharge roller assembly for a sheet feeding apparatus includes an upper cylindrical exit roller mounted on a rotatable drive shaft and a lower cylindrical pinch roller having a wheel attached to one end. The pinch roller has a length that is longer than the length of the exit roller and is moveable into contact with the exit roller so as to form a nip for gripping a print media to be discharged. The wheel has a diameter that is larger than that of the pinch roller and an outer circumferential edge composed of a plurality of protruding contact portions arranged in a radial pattern. The wheel is positioned so that the wheel can contact the media sheet being gripped and cause the sheet to deform temporarily, thereby making the sheet more rigid.
