Abstract

PURPOSE:To achieve the easy analysis of running-in, abnormalities and faults by providing one or more releasing switches. CONSTITUTION:The 1st-3rd releasing switches 111-113 are provided and are connected to a copy start control circuit 114 and copy sequence control circuit 117 by way of diodes 168, 169, NAND circuits 161-163, diodes 164-166. Then, when the 1st releasing switch 111 is turned ON, the control input to an exposure lamp lighting circuit 131 and fixing heater driving circuit 134 is inhibited and at the same time the releasing of the respective detecting means of jam, cassette setting and transfer paper presence or not is accomplished, whereby the running-in is executed. When the 2nd releasing switch 112 is turned ON, further the light source abnormal lighting detecting means is released and inputs are continuously applied to the respective circuits 126-128, 131 of optical fan driving, main drive motor driving, optical clutch driving and exposure lamp lighting. When the 3rd releasing switch 113 is turned ON, the output of a developer concentration detecting circuit 157 is inhibited and the abnormal detecting means 170 is released.
