F-2-30
The power supply converts AC voltages ranging from 100 V to 240 V from the AC inlet to DC voltages for driving the ICs, motor, and others.
The voltage generator circuits include the +32 V generation circuit for driving motors, fans, and the +5.1V generator circuit for driving sensors, logic circuits.
When in the power saving mode, the power supply cut outs the +32 V and the +5.1 V.
Power ON/OFF operation is controlled by the main controller PCB. When the upper cover is open, the power supply cut outs only the +32V power to the carriage.
