Laser scanner unit 3 2 4 1 6 5 Diversion mirror Figure 4-1-6 Laser scanner unit Name 1 Laser diode 2 Cylindrical lens 3 Polygon mirror (motor) 4 F-theta lens 5 Sensor mirror 6 Pin photo sensor Description Emits diffused, visible laser. Compensates the vertical angle at which the laser beam hits a polygon mirror segment. Has six mirror segments around its hexagonal circumference; each mirror corresponding to one scanned line width on the drum when laser beam scans on it. The f-theta lens equalizes focusing distortion on the far ends of the drum. Bends the very first shot of a laser scan towards the beam detection sensor (6). When shone by the sensor mirror above, this photo-sensor generates a trigger signal for the engine controller to start activating the paper feeding system. FS-1050 4-8
