■ General description
Main Controller
Engine controller is the circuit to control the operation sequence of the host machine and it is
■ Overview controlled by the CPU inside the engine controller.
When the Power Switch (SW1100) is turned ON and DC power is supplied through the low
The Main Controller receives print information from the Reader and external equipment voltage power inside engine controller, CPU starts the printer operation control.
(computer, etc.). Video data is created from the received print information, and is sent to the Then, CPU drives the loads such as laser diode, motors and solenoids etc. according to the
Engine Controller. image data that is input by the main controller when status becomes stand-by mode.
There are 2 types of print information from the external equipment: engine command data to The following is the block diagram of this circuit.
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. Engine controller
In the case of receiving engine command data, printer status is returned to the external
equipment after communicating with the Engine Controller.
