    摘要： When initially routing a continuous web along a path, the web walks across the width of the path, and uneven tension occurs causing the web to break in some cases when printing tension is applied thereto. Further, uneven web tension is produced on the right and left of the web by excessive walk control resulting from an excessive deviation of the web from the target position of a walk controller, with the result that the web is crumpled and broken. These problems are solved by maintaining a web tension that is lower than the printing tension until the web position converges on the target position of the walk controller after loading of the web, thereby reducing the amount of correction by the walk controller and the amount of web lost in the preparatory phase before printing, with the result that excellent image quality free from crumple or breakdown is ensured.

    摘要翻译： 当最初沿着路径布置连续卷材时，幅材横过路径的宽度，并且在打印张力被施加到其上的某些情况下，发生不均匀的张力，导致纸幅断裂。 此外，由于纸幅从步行控制器的目标位置的过度偏离导致的过度的步行控制，在幅材的右侧和左侧产生不均匀的幅材张力，结果是幅材被弄皱和破裂。 这些问题通过保持低于打印张力的卷筒纸张力来解决，直到卷筒纸位置在卷筒纸加载之后收敛到步行控制器的目标位置，从而减少了步行控制器的校正量和卷材的数量 在打印之前的准备阶段失去了效果，从而确保了没有褶皱或破裂的优异图像质量。

    摘要： An image recording apparatus for recording a two-color image on both surfaces of a continuous recording medium includes a toner image recording portion which has a toner carrier and transfers a toner image formed on a surface of the toner carrier onto the recording medium, a tractor for feeding the recording medium on which the toner image is transferred, and a both side fixing machine for receiving the recording medium fed by the tractor to fix the toner image transferred on the recording medium. In this image recording apparatus, guide rollers come into contact with non-printing portions on both side ends of the recording medium to apply tension to the recording medium by a spring and thereby gives a predetermined slack to the recording medium to absorb a difference in speed resulted between the tractor and the both side fixing machine.

    摘要： An application device includes a conveyer to convey a recording medium, an application roller to apply a treatment liquid to the recording medium, a pressure roller to sandwich the recording medium with the application roller to press the recording medium against the application roller, and a winding member to form a curved conveying path to have the recording medium curved along a conveying direction to wind the recording medium around the pressure roller. The pressure roller comes in contact with the application roller when applying the treatment liquid and separates from the application roller when not applying the treatment liquid. A predetermined positional relationship is maintained between the pressure roller and the winding member while the pressure roller moves close to the application roller to be in contact with the application roller, or the pressure roller moves away from the application roller to be separated from the application roller.
