    • PROBLEM TO BE SOLVED: To make an angle of a buffer plate fall within a proper range regardless of kinds of webs.SOLUTION: A printing apparatus includes: a printing unit that forms an image on the web; a print feeding unit that feeds the web in the printing unit; a fixing feeding unit that feeds the web downstream of the printing unit in a feed direction; a buffer unit that has the buffer plate and absorbs the flexure of the web generated by a feeding difference between the print feeding unit and the fixing feeding unit by operating the buffer plate; a print feeding control unit that causes the print feeding unit to execute a deceleration operation of decelerating a feeding speed of the web when a trigger for stopping the feed of the web has occurred; and a fixing feeding control unit 112 that causes the fixing feeding unit to execute a first deceleration operation of decelerating the feeding speed of the web when the trigger for stopping the feed of the web has occurred, measures a feed amount of the web fed by the fixing feeding unit until a predetermined time elapses, and changes the first deceleration operation executed by the fixing feeding unit to a second deceleration operation based on the feed amount.
    • 要解决的问题:使得缓冲板的角度落在适当范围内,而不管卷材的种类如何。 解决方案:打印设备包括:在网上形成图像的打印单元; 一个打印进给单元,用于将纸幅馈送在打印单元中; 定影供给单元,其在进给方向上将所述纸幅向所述印刷单元的下游供给; 缓冲单元,其具有缓冲板并通过操作所述缓冲板吸收由所述打印供给单元和所述定影供给单元之间的供给差产生的所述卷材的挠曲; 打印进给控制单元,当用于停止纸幅的进给的触发发生时,使得打印进给单元执行减速纸幅的进给速度的减速操作; 以及定影供给控制单元112,其使得定影供给单元执行第一减速操作,当用于停止进料幅材的触发器已经发生时,幅材的进给速度减速,纸幅的进给量 定影进给单元直到经过预定时间,并且基于进给量将由定影供给单元执行的第一减速操作改变为第二减速操作。 版权所有(C)2013,JPO&INPIT
