Major functions of individual components are described below:
(1) Filter & power supply section
Consists of a fuse, a filter circuit to eliminate external electric noise, and a switching type
regulator to transform an AC input to +24V DC output.

(2) SA Main PCB

Controls the entire operations of the printer. It consists of CPU, ROM, RAM, FPGA, driver
circuits, etc.

(3) Operation panel (SA Opepane PCB)

A panel used to indicate the operating status of the printer and to set specifications. It consists
of 4 keys, 1 LED (Green/Red) and 1 LCD.
