    • An image forming apparatus capable of increasing the speed of successively discharging printed printing media in order to increase the overall print speed and a control method thereof. The image forming apparatus includes a first discharge roller to feed printed printing medium rearward from a print unit disposed at an inner front portion of a main body, a reverse roller to reverse a moving direction of the printed printing medium fed from the first discharge roller from a rear to a front of the main body, a second discharge roller to discharge the printed printing medium whose moving direction is reversed outside, and an intermediate discharge roller unit which is provided between the first discharge roller and the reverse roller, the intermediate discharge roller unit including a main roller, a sub discharge roller and a sub supply roller which are in contact with the main roller. While a preceding printed printing medium fed from the reverse roller is discharged between the main roller and the sub discharge roller, a following printed printing medium fed from the first discharge roller is supplied between the main roller and the sub supply roller. Accordingly, since the interval between the preceding printed printing medium and the following printed printing medium becomes shorter than that of a conventional image forming apparatus, the speed of successively discharging printed printing media increases, and as a result the overall print speed increases.
    • 为了提高整体打印速度,能够提高连续地排印印刷媒体的速度的图像形成装置及其控制方法。 图像形成装置包括:第一排出辊,用于从设置在主体的内前部的打印单元向后馈送打印的打印介质;反转辊,用于将从第一排出辊供给的打印介质的移动方向反向; 在主体的前方的后方,将第二排出辊排出到移动方向反转的印刷媒体的外部;以及设置在第一排出辊和反转辊之间的中间排出辊单元,中间排出辊 包括与主辊接触的主辊,副排出辊和副供给辊的单元。 当从反转辊供给的前一印刷印刷介质在主辊和副排纸辊之间排出时,从主辊和副供纸辊之间供给从第一排纸辊供给的下列打印介质。 因此,由于先前打印的打印介质和随后的打印介质之间的间隔变得比常规图像形成设备的间隔短,所以连续排出印刷介质的速度增加,结果整体打印速度增加。

    • A color image forming apparatus includes a plurality of mark sensing devices are arranged between a plurality of photoconductors arranged on an intermediate transfer belt to sense a mark transferred to a region of the intermediate transfer belt corresponding to an interval between successive recording media. As an exposure time to form an electrostatic latent image on a photoconductor, on which a following developer image will be formed, is determined, minimized mis-registration and consequently, improved color registration correction efficiency are accomplished. Also, automatic color registration correction is performed on per printing operation basis, resulting in improvement in image quality.
    • 彩色图像形成装置包括多个标记感测装置,布置在布置在中间转印带上的多个感光体之间,以感测转印到中间转印带的区域的标记,该标记对应于连续的记录介质之间的间隔。 作为在形成下述显影剂图像的光电导体上形成静电潜像的曝光时间,确定最小化错配,从而实现改进的颜色配准校正效率。 此外,基于每个打印操作执行自动颜色配准校正,导致图像质量的提高。
