LASER OPTICAL UNIT
3.8.1
General Description
The laser optical unit radiates the laser beam onto the photoconductive drum responding to the digital
image signals transmitted from the LGC board. to create the latent image. Image signal is converted
into the light emission signal of the laser diode on the laser driving PC board (LDR), then radiated on
the drum through the optical elements such as cylinder lenses, polygonal mirror and f
θ
lens.
The unit must not be disassembled in the field as they are very sensitive to dust and finely adjusted at
the factory.
