2-1-2 Main charging section
The main charging section consists of the main charger assembly, drum and so on. The drum is electrically charged uni-
formly by means of a grid to form a latent image on the surface.
The main charger unit charges the drum so that a latent image is formed on the surface, the shield grid ensuring the
charge is applied uniformly.
In addition, the main charger unit is equipped with the main charger cleaning motor, and it is cleaning automatically.
