(4) LED Head
Image data for each dot line from the main control board is received by the shift register and latch register.
The 4992 LED's are driven to radiate the image data on the image drum.
(5) Fuser
The fuser consists of a heater, a heat roller, a thermistor and a thermostat.
The AC voltage from the power supply/sensor board is applied to the heater controlled by the HEATON
signal from the main control board. This AC voltage heats the heater. The main control board monitors the
heat roller temperature via the thermistor, and regulates the heater roller to keep it at a designated
temperature in the menu, depending on the thickness of the paper (tray 1&2: light=165°C, medium
light=170°C, medium=175°C, medium heavy and heavy=195°C; manual feeding and power envelope
feeder: light=175°C, medium light=180°C, medium=185°C, medium heavy=190°C, heavy=195°C) by
connecting or disconnecting the AC voltage supply to the heater.
When an abnormal rise of the heater roller temperature takes place, the thermostat of the heater voltage
supply circuit becomes active and forcibly cuts the AC voltage supply.
The temperature setting of the fuser can be changed through operator panel setting.
