4. POWER DISTRIBUTION
The document feeder uses two dc power levels: +24 volts, and +5 volts.
When the main switch is turned on, the DF transformer receives the wall
outlet ac power through the ac drive board and outputs 25 volts ac to the DF
main board. Then, the dc power supply circuit on the DF main board converts
the 25 volts ac input to +24 volts and +5 volts.
+24 volts is used by the DF motor, the pick-up solenoid, and the feed clutch.
+5 volts is used by other electrical components.
