Image-formation system The DC controller controls the image-formation system according to commands from the formatter. The DC controller controls the internal components of the image-formation system to form the toner image on the photosensitive drum surface. The toner image is transferred to the paper and fused. The following are the main components of the image-formation system: ● Cartridge ● Transfer roller ● Fuser ● Laser scanner ● High-voltage power supply Figure 1-11 Image-formation system Laser scanner Cartridge Transfer roller Fuser High-voltage power supply DC controller The DC controller rotates the drum motor to drive the following components:
● Photosensitive drum ● Developing roller (follows the photosensitive drum) ● Primary charging roller (follows the photosensitive drum) ● Transfer roller The DC controller rotates the fuser motor to drive the following components: ● Pressure roller ● Fuser film (follows the pressure roller) 22 Chapter 1 Theory of operation ENWW
