The printer electrical system consists of the main controller PCB and media take-up relay PCB and power supply PCB and hard disk drive which are mounted on

the back side of the printer, the carriage relay PCB, the head relay PCB, and printhead which are mounted in the carriage, the operation panel on the right upper

cover and other electrical components such as sensors, and motors.

The main controller PCB manages the image data processing and the entire electrical system, and controls relay PCBs and driver functions.
