23.3 Parts that operate when the power switch is turned ON

A. Composition

B. Operation

Turning ON the main power switch (SW1) supplies an AC power source to DC power supply (DCPS).

In this way, each power source of 12V DC and 5V DC is supplied to the overall control board (OACB).

OACB supplies 5V DC to the operation board (OB) to be placed in the condition of standing by for the turn-ON

of the power switch (SW2).

When equipped optionally with the FAX kit (FK-502) and the hard disk (HD-505), each power source of 12V DC

and 5V DC is supplied through OACB.
