    • A method of printing an image onto a sheet in a printer having at least one print module and a transport arrangement defining a transport path for transporting sheets through the at least one print module is shown. In accordance with the method, a series of constant frame clock signals is generated and a sheet is approximately feed into a frame along the sheet transport path in accordance with the frame clock signal, wherein the frame defines a virtual desired sheet position, which moves with a predetermined speed along the sheet transport path. The sheet is transported along the sheet transport path, an in-track position of the sheet in the sheet transport path is detected and it is determined whether the in-track sheet position matches the frame within predetermined limits. If the sheet matches the frame within predetermined limits, a start of frame signal is issued at a predetermined fixed time following the generation of the frame clock signal in accordance with which the sheet was fed into the frame, wherein the start of frame signal starts generation of a latent toner image in the print module for transfer to the sheet. If the sheet does not match the frame position within predetermined limits, the start of frame signal is issued at a specified time following the generation of the frame clock signal in accordance with which the sheet was fed into the frame, wherein the specified time corresponds to the predetermined fixed time to which a time shift is added, wherein the time shift is determined on the basis of the deviation of the actual sheet. Finally, the sheet is aligned in-track in accordance with the start of frame signal, and the thus aligned sheet is transported through the print module in alignment with the latent toner image to transfer the same to the sheet.
    • 示出了在具有至少一个打印模块和传送装置的打印机中将图像打印到纸张上的方法,所述打印模块和传送装置限定用于通过至少一个打印模块传送纸张的传送路径。 根据该方法,产生一系列恒定的帧时钟信号,并且纸张基于帧时钟信号沿着纸张传送路径近似馈送到一个帧中,其中框架限定了虚拟期望的纸张位置,其随着 沿着纸张传送路径的预定速度。 纸张沿着纸张传送路径被传送,纸张在片材传送路径中的轨道内位置被检测到,并且确定轨道内片材位置是否与预定限制内的帧匹配。 如果纸张与预定限度内的帧匹配,则在生成帧时钟信号之后的预定固定时间发出帧信号的开始,根据该时钟信号将纸张馈送到帧中,其中帧信号的开始开始生成 的印刷模块中的潜在调色剂图像转印到纸张上。 如果纸张与预定限度内的帧位置不匹配,则在生成帧时钟信号之后的指定时间发出帧信号的开始,该帧时钟信号根据该帧时钟信号将纸张馈送到帧中,其中指定的时间对应于 添加时间偏移的预定固定时间,其中基于实际纸张的偏差来确定时间偏移。 最后,根据框架信号的开始将片材对准轨道,并将由此排列的片材与潜像调色剂图像对准地传送通过打印模块,以将其转印到片材上。

    • A device for controlling substrate web tension includes first and second driving units with respective driving rollers around which the substrate web is partially guided and tensioned. The first and second driving units have different rotational moments of inertia. A measuring unit measures the tension of the substrate web. A control unit has first and a second filtering units with different filtering characteristics for filtering the measured value. The control unit includes a first control device for controlling the first driving unit based on the measured value filtered by the first filtering device, and a second control device for controlling the second driving unit based on the measured value filtered by the second filtering device.

    • A method for printing a multi-color image on a web that is moved in a transport direction along a plurality of printing units for respectively printing one color separation of the multi-color image. A line clock is determined for the printing unit being the first one in transport direction, as a function of the transport speed of the web, and a plurality of synchronization marks is printed with the web, said synchronization marks located in a region of the web that is outside the region of the multi-color image, and printed at a prespecified clock that is formed of a partial set of the line clock. The synchronization marks are detected at a position between the first and the second printing units, and a line clock for the second printing unit in the direction of movement is determined based on the detection of the synchronization marks.
