Close paper exit door. Close front door. When a key counter is drawn out in the course of book copying, paper in copying is stopped by paper exit. However, when a key counter instant cut mode is selected, the main body is stopped immediately. Before the start of copying, warning is displayed. After the start of copying, the main body is stopped after ejecting all papers under processing, and warning is displayed. When a key counter is drawn out in the course of book copying, paper in copying is stopped by paper exit. In the case of occurrence in collective reading, warning display and guidance by MSG are conducted, and when ADF is used, an original is ejected forcedly for the stop. In the case of occurrence in real time output, warning display and guidance by MSG are conducted after completion of partial output. The main body is stopped immediately if it is in process of copying. Only in idling, "draw out tray 3" and "remove paper" are displayed on detection MSG. Mount a key counter. In this case, resetting is made to initially set state. However, in the case of instant cut mode, remove jammed paper, if any. Insert connector after turning main switch OFF, and then turn it ON.
