    • In order to reduce the number of signal lines of the cable between the controller and the carriage and to allow the print timing of each head to be adjusted in increments smaller than one pixel, the signal lines include a line for carrying serial print data to be supplied to a plurality of print heads in a predetermined order, a line for carrying a clock signal corresponding to individual bits of the data, lines for carrying signal HDSEL[1 . . . 0] indicating which print head corresponds to which print data included in the serial print data, and lines for driving the heads. When data is transferred over this cable, one slice section is divided into a plurality of sections, the slice section corresponding to a time slot required to transfer a unit of print data corresponding to a plurality of dot printing elements of the plurality of heads, each divided section is further divided into a number of subsections the number of which is equal to the number of the print heads. The transfer of the print data of each print head is started independently of the print data of other print heads, beginning with its arbitrary subsection.
    • 为了减少控制器和滑架之间的电缆的信号线的数量,并且允许以小于一个像素的增量调整每个磁头的打印定时,信号线包括用于承载串行打印数据的行 以预定顺序提供给多个打印头,用于承载对应于数据的各个位的时钟信号的行,用于传送信号HDSEL的行[1]。 。 。 0]表示哪个打印头对应于串行打印数据中包括的打印数据以及用于驱动打印头的行。 当通过该电缆传送数据时,一个片段被分成多个部分,片段对应于传送与多个头的多个点打印元件相对应的打印数据的单位所需的时隙,每个 分割部分进一步划分成若干子部分,其数量等于打印头的数量。 每个打印头的打印数据的传送与其他打印头的打印数据独立地开始,以其任意小节开始。

    • An image forming apparatus has an intermediate transfer belt stretched lightly across rollers to move endlessly in a sub-scanning direction upon image formation and has an outer surface to which a toner image formed by a development unit is transferred. A secondary transfer opposing roller is one of the rollers across which the intermediate transfer belt is stretched. A secondary transfer roller contacts the outer surface of the intermediate transfer belt and transfers the toner image on the intermediate transfer belt to recording paper. A movement mechanism moves at least one of the rollers or the secondary transfer roller and changes a pressed state of the intermediate transfer belt by the secondary transfer roller at a nip of the secondary transfer opposing roller and the secondary transfer roller. A movement mechanism control unit controls a travel distance of the roller to be moved by the movement mechanism.
    • 图像形成装置具有中间转印带,该中间转印带轻轻地横过辊子,在成像时在副扫描方向上不停地移动,并且具有由显影单元形成的调色剂图像被转印到的外表面。 二次转印相对辊是中间转印带被拉伸的辊之一。 二次转印辊接触中间转印带的外表面并将中间转印带上的调色剂图像转印到记录纸上。 移动机构移动至少一个辊或二次转印辊,并且在二次转印对置辊和二次转印辊的辊隙处,通过二次转印辊改变中间转印带的按压状态。 移动机构控制单元控制由移动机构移动的滚子的移动距离。
