9. AC POWER AND DC POWER DISTRIBUTION
When this copier is plugged in and the main switch is turned off, ac power is
supplied via the ac drive board to the anti-condensation heater. When the
front cover and/or the exit cover is open, the cover safety switch completely
cuts off power to all ac and dc components. The RAM board has a back up
power supply (dc battery) for the service program mode and misfeed job
recovery.
When the main switch is turned on, the ac power supply to the
anti-condensation heater is cut off and ac power is supplied to the ac drive
board. The main transformer receives wall outlet ac power through the ac
drive board and outputs 10 volts ac and 26 volts ac to the main dc power
supply board and the option dc power supply board.
