The machine's laser scanner assembly consists of the laser driver and the scanner motor, which are driven by signals
coming from the engine controller.
The laser driver serves to turn on the laser diode according to the laser control signal and video signals from the
engine controller.
The laser beam moves thorough the collimator less and the cylindrical lens to reach the 4-facet mirror rotating at a
specific speed.
The leaser beam reflected by the 4-facet mirror moves through the imaging lens arranged in front of the 4-facet mirror
and the reflecting mirror to reach and focus on the photosensitive drum.
