(4) LED head
The shift and latch registers receive image data from the main control board for each dot line. 4,992 LEDs are driven to
radiate the image drum.
(5) Heat Assy
The 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 signal from the main control board to
heat the heat roller. The main control board monitors the heat roller temperature via the thermistor and keeps the
temperature constant by turning on/off the heater AC voltage supply.
If the heat roller temperature rises abnormally, the thermostat of the heater voltage supply circuit functions to forcibly
suspend the AC voltage supply.
