Controller System

Main Controller

■ Overview

The Main Controller receives print information from the Reader and external equipment
(computer, etc.). Video data is created from the received print information, and is sent to the

Engine Controller.

There are 2 types of print information from the external equipment: engine command data to
exchange the status or unique information of a printer and dot data for printing.
In the case of receiving dot data, video data is created and is sent to the Engine Controller.
In the case of receiving engine command data, printer status is returned to the external
equipment after communicating with the Engine Controller.

Engine Controller

■ General description

Engine controller is the circuit to control the operation sequence of the host machine and it is
controlled by the CPU inside the engine controller.
When the Power Switch (SW1100) is turned ON and DC power is supplied through the low
voltage power inside engine controller, CPU starts the printer operation control.
Then, CPU drives the loads such as laser diode, motors and solenoids etc. according to the
image data that is input by the main controller when status becomes stand-by mode.
The following is the block diagram of this circuit.
