    • In a printing apparatus, even when the measured paper size differs from the scheduled size, it is possible to reduce the frequency of requiring a recovery procedure, and prevent the productivity from decreasing by continuing the operation of the printing apparatus as much as possible. The printing apparatus includes a paper feeding unit for feeding a print sheet from a paper feed tray 120, 130a, 130b, 130c or 130d to a transportation route CR through a paper feed route FR, in-tray sensors 182, 183a, 183b . . . for measuring the paper size in the paper feed trays; a transportation sensor 181 for measuring the paper size on the transportation route, a transportation operation adjusting unit 332 for adjusting the transportation operation on the transportation or paper feed route according to the measurement result of the transportation sensor 181 when the measurement results of the transportation sensor 181 and in-tray sensors mismatch.
    • 在打印装置中,即使当测量的纸张尺寸与预定尺寸不同时,也可以减少需要恢复过程的频率,并且尽可能地继续打印装置的操作来防止生产率降低。 打印装置包括一个送纸单元,用于通过供纸路径FR,托盘传感器182,183a,183b将打印纸从供纸托盘120,130a,130b,130c或130d馈送到运送路径CR。 。 。 用于测量进纸盘中的纸张尺寸; 用于测量运输路线上的纸张尺寸的运输传感器181,当运输传感器的测量结果时,根据运输传感器181的测量结果来调节运输或供纸路线上的运输操作的运输运行调节单元332 181和托盘传感器不匹配。

    • In an image forming apparatus, a sheet reversing mechanism is configured to take over and transfer, at a transfer speed Vr, a print sheet with an image already formed on one side being transferred at the transfer speed Vr from a first transfer mechanism, to stop the print sheet once, then to start transfer of the print sheet in an opposite direction, and to pass the print sheet to a second transfer mechanism at the transfer speed Vr. The first and second transfer mechanisms are located on upstream and downstream of a switchback reverse path for reversing print sheets respectively Upon lapse of a time T1 after detection of the print sheet by a print sheet detection unit, a transfer control unit drives the sheet reversing mechanism to start acceleration from a stopped state to the transfer speed Vr, the time T1 calculated based on the transfer speed Vr.
    • 在图像形成装置中,纸张反转机构被构造成以传送速度Vr接收并以从传送速度Vr从第一传送机构传送的图像已经形成的图像传送到停止 打印纸一次,然后以相反的方向开始传送打印纸,并且以转印速度Vr将打印纸传送到第二传送机构。 第一传送机构和第二传送机构分别位于翻转反转路径的上游和下游,分别用于反转打印片材。当通过打印片材检测单元检测到打印片材之后经过时间T1时,传送控制单元驱动片材反转机构 从停止状态开始加速到传送速度Vr,基于传送速度Vr计算出的时间T1。
