The main or drum motor is a pulse motor of 48 steps/rotation with two-phase excitement by the signalfrom the main control board and is the main motor of this mechanism.(4) LED HeadImage 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) FuserThe 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 HEATONsignal from the main control board. This AC voltage heats the heater. The main control board monitors theheat roller temperature via the thermistor, and regulates the heater roller to keep it at a designatedtemperature in the menu, depending on the thickness of the paper (tray 1&2: light=165°C, mediumlight=170°C, medium=175°C, medium heavy and heavy=195°C; manual feeding and power envelopefeeder: light=175°C, medium light=180°C, medium=185°C, medium heavy=190°C, heavy=195°C,transparency = 160°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 voltagesupply circuit becomes active and forcibly cuts the AC voltage supply.The temperature setting of the fuser can be changed through operator panel setting.Copyright 1997, Okidata, Division of OKI America, Inc.
