How the wireless radio works
The wireless radio broadcasts on the 2.4 GHz frequency whenever the wireless
radio is powered on and enabled.
The wireless radio automatically turns off when the printer is powered off or
unplugged from a power source.
If the printer is connected to an active Ethernet network with an Ethernet cable, the
wireless radio remains active, but the printer does not attempt to make a wireless
connection.
Note: USB connections have no effect on the radio's functionality.
