Abstract: An excessive heating protection circuit to be connected to a first temperature sensor being configured to output less voltage with a rise in temperature and a second temperature sensor being configured to output more voltage with a rise in temperature. The excessive heating protection circuit includes: a multiplexer having a plurality of channels capable of receiving reference voltages predetermined for the first and second temperature sensors, the multiplexer being configured to output one of the reference voltages by selecting one of the channels with reference to input selection signals; a first comparator being configured to compare the output voltage of the first temperature sensor to the output reference voltage of the multiplexer and to output a comparison result; and a second comparator being configured to compare the output voltage of the second temperature sensor to the output reference voltage of the multiplexer and to output a comparison result.

Abstract: A serial tandem image forming system is described which is capable of inhibiting both the degradation of image quality and the reduction of the productivity. This system consists mainly of the control units of upstream and downstream apparatuses. When a preceding sheet differs from the subsequent sheet in sheet type, a control unit for controlling the image forming system has the subsequent sheet stand by at a paper stop roller of the upstream apparatus, and performs the operation of switching the operating states of the upstream and downstream apparatuses in accordance with the sheet type of the subsequent sheet. Also, the control unit predicts the timing of finishing the switching of the operating state, and then re-starts the conveyance of the subsequent sheet, in advance of finishing the switching of the operating state, by controlling the paper stop roller on the basis of the predicted finishing timing.
