iPF810 / iPF820
F-2-36
The power supply converts AC voltages ranging from 100V to 240V from the AC inlet to DC voltages for driving the ICs, motor, and others.
The voltage generator circuits include the +32V 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 out the +32V and the +5.1V.
Power ON/OFF operation is controlled by the main controller PCB. When the upper cover is open, the power supply cut out only the +32V power to the carriage.
