Turn the wireless radio on and off
The wireless radio is on by default, as indicated by the blue light on the front of the printer. In
order to stay connected to a wireless network, the radio must stay on. However, if your printer is
connected to a wired network or you have a USB connection, the radio is not used. In this case
you might want to turn the radio off.
Touch (right arrow), touch Setup, and then touch Network.
Touch Wireless, and then touch On to turn on the radio, or touch Off to turn off the radio.
