Abstract

PURPOSE:To enhance the reliability of the device, by continuously monitoring for trouble of each part of the image forming device with a first detecting means, and periodically monitoring the state of jam detection sensor with a second detecting means. CONSTITUTION:Trouble or other state of each part of the image forming device may be always monitored on lamps through control computer Q1, sequence control computer Q2, automatic original feeding computer Q3, etc. When a diagnostic operator manipulates specified switches in specified time zone, the input port terminal 9 of the computer Q1 becomes low level to set in diagnostic mode. Then, as the copying action is started, the timing of producing detection outputs of jam preventive recording member oblique travel detection sensor, jam detection sensor, etc. may be judged in a logic circuit containing ROM, counters, etc., so that trouble of jam preventive detection sensor, jam detection sensor and others may be judged.
