What do I do if the wireless light on the printer is not lit?
If the blue light on the printer control panel is not lit, wireless may be turned off. To turn it on, swipe down the tab at the top of the screen to open the Dashboard, touch the Wireless icon, touch Settings, touch Wireless Settings, and then touch Wireless to enable it. (Page 1)
