Abstract

PURPOSE:To immediately stop a signal to an actuator and to prevent the spread of an abnormal condition when abnormality occurs by supplying an output control signal from the microcomputer of a copying machine to the actuator concerned with the response of a monitor device instead of directly supplying it to said actuator. CONSTITUTION:The inputted information of sensors 10, 11 and the output control signal to the actuator are communicated from the microcomputer 1 of the copying machine to the microcomputer 14 of the monitor device 13 by an appropriate communication means. The microcomputer 14 monitors sensor information and the output control signal to the actuator. When those serial signals disagree with image forming sequence, the action of a subsequent actuator, which is caused by the output control of its previous actuator is displayed by a seven segment displaying device 22 as the cause of malfunction. Thus, the cause of the malfunction can be easily identified and the spread of the abnormal condition can be prevented.
