LASER OPTICAL UNIT

The laser optical unit radiates the laser beam onto the photoconductive drum responding to the digital

image signals transmitted from the scanner, USB, network, etc. 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 fθ lens.

The unit must not be disassembled in the field as they are very sensitive to dust and finely adjusted at

the factory.
