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.
