The machine's laser exposure system serves to form a static (latent) image on the surface of the photosensitive drum according to the video signals from the main
controller, and it consists of 2 laser driver PCBs, a BD circuit (Note 1), and a scanner motor among others.
These components are constructed as a single entity (scanner unit), and are controlled by the DC controller.
