11.4.1 Power Supply
11.4.1.1 Low-voltage Power Unit
0020-2570
The low-voltage power PCB is to convert AC into DC covering the DC loads.
F-11-3
The low-voltage power PCB is partially activated as soon as plugged in the electrical outlet. When turning ON the power switch (SW4), whole low-voltage power
supply works.
The AC power is then converted into +24V, +5V and +3.3V covering each of machine DC loads. The following are the main loads for each power.
+24V:
Main controller PCB, high-voltage power PCB, Motors, solenoids, fans, reverse unit, and ADF
+5V:
Main controller PCB, driver PCB, laser driver PCB, high-voltage power PCB, memory controller PCB, color displacement/density sensor, and control
panel
+3.3V:
DC controller PCB, main controller PCB, driver PCB, high-voltage power PCB, memory controller PCB, sensor (photo interrupter), environment sensor,
fixing unit, control panel, reverse unit, and ADF
