PURPOSE:To simplify a circuit and to reduce the cost of a device by controlling a main motor, a fixing temperature, the light quantity of a light emitting diode, a polygon mirror driving motor and dot density by means of a computer. CONSTITUTION:The main motor 2, a heater for fixation 3, the light emitting diode 4, a dip switch 5 and the polygon mirror driving motor 6 are connected to the computer 1. The computer 1 performs with PWM control of the main motor 2, the control of the fixing temperature by turning on and off the heater for fixation 3, the control of the light quantity of the light emitting diode 4, the control of the dot density with the aid of a dot density switching signal and the PWM control of the polygon mirror driving motor 6. Thus, control circuits are reduced and the simplification of the circuit and the reduction of cost are contrived. |
