Xerographic Process-Laser Exposure

Laser Unit (Exposure)

The laser unit is equipped with the Vertical Cavity Surface Emitting Laser (VCSEL) technology.
40 laser beams are emitted to produce 2400dpi×4800dpi.
Laser beams are reflected on the polygon mirror and lenses to create a latent image on each of the
photoconductive drums by imparting static electricity on the surface of the drum.
