Operation panel
POWER ON
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 +26 V generation circuit for driving motors, fans, and sensors and a +21.5 V generator circuit for driving sensors, heads,
logic circuits, and others.
When the power is turned off, +26 V and +21.5 V are reduced to about 12 V and 9 V respectively (power save mode).
Power ON/OFF operation is controlled by the main controller PCB.
