Image formation system
The image formation system serves as the nerve center of the printer and forms a toner image on
paper. It is controlled by the DC controller. The DC controller controls the laser/scanner unit and the
high-voltage power supply PCB to form an image on paper according to the VIDEO signals (VDO, /
VDO) upon reception of a print command from the formatter. There is a memory tag inside each
cartridge. The memory tags read and write data according to the command from the DC controller.
