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).
6 Pin photo sensor	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.
