Fusing Temperature Control Circuit
The thermister TH1 detects the surface temperature of the fusing heat roller, and input analog voltage into IC201-78. According to the detected temperature, the heater lamp H1 is turned On or Off by the heater lamp On Off signal, which is input by IC201-55, and controls the temperature of the fusing part. The heater lamp is 450W. 3 different voltages are used according to the destination 100V, 120V and 230V. If the heat lamp is not turned off even when the thermister detects abnormally high...
