2.1 Power Supply
2.1.1 Outline
The machine's DC power is generated by the AC power received by the power supply
PCB. The generated DC power is converted into a full-time ON system (linked to the power
switch) and a remote ON/OFF system (linked to control signals), and is supplied to each
load.
The output of the power supply PCB is controlled by the power switch (SW101) or sig-
nals from the printer board.
The names and functions of the parts associated with the power supply are as follows:
