;
The power switch is connected to the secondary side of the electrical circuit. Since it has a delay
circuit, voltage is still applied for the specified period of time after the printer power is off.
;
As long as the printer is plugged in, voltage is applied to the primary side of the electrical circuit.
Therefore be sure to unplug the printer before servicing or replacing the interface.
