6.1.1 Outline
Below illustration shows the construction of the image formation system.
The machine is a cartridge type, in which the core of its image formation components are constructed as a signal
entity: photosensitive drum, primary charging roller, developing cylinder, cleaning blade, and toner housing.
The DC controller PCB has a built-in high-voltage output assembly, and generates high voltage for charging at such
times as necessary.
