The AC, DC, and
AC power distribution
The AC power circuitry supplies AC voltage whenever the power cord is connected to the AC power source. The AC voltage is distributed to the DC power supply circuitry and to the AC driver circuitry, which controls AC voltage to the fusing assembly's heating element.
DC power distribution
The DC power distribution circuitry, located on the ECU, distributes +5 VDC and +12 VDC as follows:
3
+5 VDC: | Formatter |
| Photosensors |
| |
| |
+12 VDC: | Motor |
| Scanner motor |
| Solenoid |
+12VADC: | |
