0008-6352
The printer electrical system consists of the system controller, engine controller, and power supply, all of which are mounted at the rear of the printer; the
carriage relay PCBs, head relay PCBs, and printhead, which are located in the carriage unit; the operation panel on the upper right cover; and other electrical
components, such as the sensors and motors.
The system controller manages image data, and the engine controller manages all electrical components. The other relay PCBs and drivers control the
various functions under the management of the engine controller.
