A power supply switching apparatus for a facsimile machine includes a power supply switch, a switch controller and a capacitor-based power supply. The power supply switch is configured to selectively couple and decouple a power supply to a facsimile machine. The switch controller is communicatively coupled to the power supply switch and is configured to control the power supply switch in response to the satisfaction of one or more switch criteria. The capacitor-based power supply is communicatively coupled to and provides power to the power supply switch, for example, when the power supply switching apparatus is operating in a standby mode, or any other time the switch controller needs power. Other embodiments include the use of a second power supply to recharge the capacitor-based switch power supply and a switch trigger instead of a switch controller.
