Image-formation system The image-formation system forms a toner image on media. The product includes four print cartridges that contain the toner that is used to create the image on the media. Toner is applied in the following order, using only the colors necessary for a specific image: yellow (Y), magenta (M), cyan (C), and black (Bk). The following items are the main components of the image-formation system. ● Print cartridges ● ITB ● Laser scanner ● Fuser The DC controller controls the laser/scanner unit and the high-voltage power unit to form the toner image on the ITB according to the video signals, and then to transfer and fuse the image on the media.
