F-2-2

T-2-2

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 4facet mirror rotating at a

specific speed.
