    • 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 duplexing module that is attachable to a printer that has a simplex media-handling system. The duplexing module is used in conjunction with the simplex system to carry out the print media handling (flipping) that is required for duplex printing. The module includes a single drive roller and an entry guide. The printer feed roller moves the printed media sheet along the entry guide to the drive roller of the duplexing module. The duplexing module includes an exit guide that extends between the drive roller and the feed roller. The print media (having one side printed) moves with the rotated drive roller until it reaches the exit guide. The printed side of the print media is thus directed against the feed roller of the printer so that the opposite side of the media is presented for printing.
    • 可连接到具有简单介质处理系统的打印机的双面打印模块。 双面打印模块与单面系统一起使用,以执行双面打印所需的打印介质处理(翻转)。 该模块包括单个驱动辊和入口导向件。 打印机进纸辊将打印介质纸张沿入口导板移动到双面模块的驱动辊。 双面模块包括在驱动辊和进给辊之间延伸的出口引导件。 打印介质(具有一面打印)随着旋转的驱动辊移动,直到其到达出口导板。 因此,打印介质的打印面被引导到打印机的进给辊上,使得介质的相反侧被呈现用于打印。
