PURPOSE:To take a heat running excellently and obtain an invariably excellent image by inhibiting freely the control operation of a detecting means which inhibits processing operation on detecting the improper state of a processor. CONSTITUTION:Input signals for detecting the improper state of the processor are obtained by respective sensors and inputted to a microcomputer through a matrix circuit, and a control signal for every sequence operation is outputted through a control circuit to inhibit the processing operation corresponding to the improper state. When a flag 1 is in an area corresponding to the sequence in the RAM of the microcomputer through a keyboard, etc., this is outputted as a jump signal to skip the control process by the microcomputer which corresponds to the detection signal of the corresponding sensor, thereby inhibiting its control operation. For the purpose, a desired running test wherein a desired sequence step is skipped is taken and the heat running test is performed excellently to perform excellent image formation all the time. |
