Abstract

PURPOSE: To enhance the reliability, by providing a diagnostic mode for continuously monitoring each part of the device for fault and another diagnostic mode for checking fault at specified time, and checking the detection action of the sensor for taking action timing.
CONSTITUTION: The image of the original is formed on a photoreceptor on the surface of a drum 11. The constitution includes a processing means for executing the image forming cycles, a means for continuously detecting the operating state of the processing part, and a means to check for fault at specified time. In order to facilitate fault checking by the user side, the electric parts to be checked are detected by upper oblique line sensor 37, lower oblique line sensor 36, paper transfer sensor 35, second resist sensor 39, and paper discharge sensor 40, and a jam display is indicated if fault is found, so that the fault checking may be facilitated. Hence, the downtime can be decreased.
