The relationship between the mainmotor, electromagnetic clutch, resist gear, drum gear, hopping roller is shown in the tablebelow and on the subsequent pages.(4) LED headThe shift and latch registers receive image data from the main control board for each dot line.2,496 LEDs are driven to radiate the image drum.(5) Heat AssyThe heat Assy consists of a heater, a heat roller, a thermistor, and a thermostat.The power supply unit supplies AC voltage to the heater according to the HEATON signalfrom the main control board to heat the heat roller. The main control board monitors the heatroller temperature via the thermistor and keeps the temperature constant by turning on/offthe heater AC voltage supply.If the heat roller temperature rises abnormally, the thermostat of the heater voltage supplycircuit functions to forcibly suspend the AC voltage supply.
