    • A modular duplex media handling system used in conjunction with a simplex media handling print recording apparatus, includes a drive roller having a simple gear linkage. The simple gear linkage provides a fixed rotational relationship between the drive roller and a feed roller of the simplex handling apparatus. A media guide pivots about the drive roller's axle between a first position into which it is biased, and a second position into which it is deflected by a media sheet. From the first position, a media sheet retracting from a print zone can enter the duplex media handling system. From the second position, a media sheet can move from the input tray around the feed roller into the print zone, or move out of the duplex media handling system back into the input tray to await refeeding for second side printing.
    • 与单面介质处理打印记录装置结合使用的模块化双面介质处理系统包括具有简单的齿轮联动的驱动辊。 简单的齿轮联动装置在单面装卸装置的驱动辊和进给辊之间提供固定的旋转关系。 介质引导件绕驱动辊的轴枢转在被偏置到其中的第一位置和第二位置之间,其被介质片偏转到其中。 从第一位置开始,从打印区缩回的介质页可以进入双面介质处理系统。 从第二位置,介质片材可以从进纸盘周围的输入托盘移动到打印区域中,或者从双面打印介质处理系统移出回到进纸盒中,以等待第二面打印的重新进纸。

    • A media handling system for handling sheets of media. The system includes a pick roller having a circumferential media-contacting surface and arranged for rotation about a roller axis to contact and pick a sheet from an input source. A drive roller rotates about a drive roller axis, with a media path extending between the pick roller and the drive roller. A first guide structure is positioned along a first longitudinal edge of the media path and providing a first media guide surface. A second guide structure is positioned along a second longitudinal edge of the media path and provides a second media guide surface. The first and second guide surfaces are positioned to constrain the movement of a media sheet in the media path between the pick roller and the drive roller, thereby alleviating trailing edge print defects.

    • A media handling system includes a drive roller, an elongated pinch roller and a contoured support. The pinch roller extends across the print medium near the print zone to control the localized shape of the print medium. The support underlies the print medium in the print zone and includes first and second underlying pivotal inclines. The pinch rollers push the print medium onto the first pivotal incline adjacent to the drive roller. The second underlying incline is located downstream toward the print zone exit. As the print medium is fed through the print zone, a portion of the print medium within the print zone between the pivotal inclines is suspended exhibiting a reverse bowing. Beyond the second pivotal incline the print medium droops. The presence of the two underlying inclines more uniformly distributes the stress accompanying the bowing of the print medium within the print zone.
    • 介质处理系统包括驱动辊,细长夹送辊和轮廓支撑。 夹紧辊在打印区域附近延伸穿过打印介质,以控制打印介质的局部形状。 支撑件位于打印区域中的打印介质的下面,并且包括第一和第二下面的枢轴倾斜。 夹送辊将打印介质推到与驱动辊相邻的第一枢轴倾斜处。 第二个下倾斜位于印刷区出口的下游。 当打印介质通过打印区域进给时,位于枢转倾斜之间的打印区域内的打印介质的一部分被悬挂,呈现出反向弯曲。 超越第二个关键倾斜的打印媒介下垂。 两个下面的倾斜的存在更均匀地分布在打印区域内伴随着打印介质的弯曲的应力。
