What does it mean when the Wireless light is blinking and the Wireless Attention icon is on?
When the Wireless light is blinking and both the Wireless icon and the Wireless Attention icon are on, there is no wireless signal. You should make sure your wireless router or access point is powered on, and move the printer closer to the wireless router. (Page 8)
