11.2  Functions

(1)Drum

The drum is made of a cylindrical aluminum base coated with thin film of organic photoconductive substance.

The photoconductive object becomes insulative (the electrical resistance is high) when it is not exposed to the light and electrically conductive (the electrical resistance is low) when it is ex- posed to the light. This object is called a photoconductor.

(2)Main charger

The main charger consists of a metal rod with U-shaped section, insulated blocks at both ends of the rod and charger wire attached between them.

When a high voltage is applied to the charger wire, the air around it is charged (ionized). The ion- ized air then flows into the drum causing it to be charged. This phenomenon is called “corona dis- charge”. Negative charge caused by the corona discharge and grid is applied to the drum surface evenly in dark place. The main charger is equipped with a wire cleaner to clean the wire.

(3)Cleaner

(a)Cleaning blade

This blade is pressed against the drum surface with a constant force by the pressure springs, and scrapes off the residual toner from the drum surface.

(b)Recovery blade

This blade catches the toner scraped off by the cleaning blade.

(c)Toner recovery auger

This auger carries the residual toner scraped off to the toner bag.

(d)Toner bag full detection sensor -1

The sensor detects the toner bag full when it is pushed by the toner recovery auger in the cleaner which is given a pressure from the used toner in the toner bag.
