23.3.1 Parts operated when the main power switch is turned ON
• When the Main power switch is turned ON, MFP board detects it and sends a control sig-
nal to the DC power supply through the printer control board.
• The DC power supply then supplies 3.3 V DC, 5V DC, 12V DC, 15 V DC, and 24 V DC to
all boards and options. It also turns ON the relays in the PWBs, preparing AC power
ready to be supplied to each heater lamp.
