What should I do if the blue wireless light on my printer is not lit?
The blue light not being lit means wireless might be turned off. To turn on wireless, touch or swipe down the tab at the top of the screen to open the Dashboard, touch Wireless, then touch Settings. Touch Wireless Settings, and then touch Wireless to turn it on.
