Name Description

1 Laser diode Emits diffused, visible laser.

2 Cylindrical lens Compensates the vertical angle at which the laser beam hits a polygon

mirror segment.

3 Polygon mirror (motor) 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.

4 F-theta lens The f-theta lens equalizes focusing distortion on the far ends of the

drum.

5 Sensor mirror Bends the very first shot of a laser scan towards the beam detection

sensor (6).

a trigger signal for the engine controller to start activating the paper
