    • During first side printing a media sheet is fed along a first media path from feed rollers to metering rollers and into a print zone. After first side printing, the metering roller stops prior to releasing the media sheet into the output tray. The metering roller reverses direction to move the media sheet back along the first media path onto the feed roller, and into the modular duplex handling system. The media sheet is flipped, then fed back for second side printing. Second side printing is performed in either one of book mode or tablet mode. In book mode, the top of the page is the same edge of the media sheet for the first side and the second side. In tablet mode, the media sheet edge at the top of the first side corresponds to the bottom of the second side.
    • 在第一侧打印期间,介质片材沿着第一介质路径从进给辊进给到计量辊并进入打印区域。 在第一面打印之后,计量辊在将介质纸张释放到出纸托盘之前停止。 计量辊反转方向,将介质纸张沿着第一介质路径移动到进纸辊上,并进入模块化双面处理系统。 介质片翻转,然后反馈给第二面打印。 在书本模式或平板电脑模式下进行第二面打印。 在书本模式下,页面的顶部与第一面和第二面的介质薄片的边缘相同。 在平板模式下,第一侧顶部的介质片边缘对应于第二面的底部。

    • 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。
