Operation
a.
Shift from Standby to Sleep Mode
The timer on the MFC PCB keeps track of lapses of time, and it issues a sleep mode shift
command when a specific period of time passes. In response to the sleep shift command, the DC
controller PCB causes the DC_POWER_OFF signal to go '0' and the A_REMOTE signal to go '0'.
In response to the A_REMOTE signal=0, the relay circuit switches the power supply to sleep
mode.
