4 Image Formation System

4.1 Outline

F04-401-01 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 cyl-
inder, 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.
