摘要：
A transfer member to transfer a document at different transfer speeds according to transfer sections of a document transfer path includes a first transfer roller and a second transfer roller, both of which are respectively mounted at upstream and downstream sides of the document transfer path, and a driving unit to drive the first and second transfer rollers such that the speed of the second transfer roller is higher than that of the first transfer roller under the control of a control unit is further included. The control unit reads an image pattern on a test document using a read device, acquires speed compensation information to compensate for a transfer speed of the transfer member, and controls an operation of the transfer member according to the speed compensation information at the time of transferring the document.
摘要（中）：
根据文件传送路径的传送部分以不同的传送速度传送文件的传送部件包括分别安装在文档传送路径的上游侧和下游侧的第一传送辊和第二传送辊，第二传送辊和第二传送辊 驱动单元以驱动第一和第二转印辊，使得在控制单元的控制下第二转印辊的速度高于第一转印辊的速度。 控制单元使用读取装置读取测试文件上的图像图案，获取速度补偿信息以补偿传送构件的传送速度，并且在传送时根据速度补偿信息控制传送构件的操作 文件。
