The blinking WiFi light on your printer indicates either your printer is trying to communicate with your wireless network or your printer is not connected at all. For a quick fix, try to disconnect your printer from the power outlet. Power cycle your router and reboot your computer. Then, power on your router first, then your printer and lastly your computer. Check the WiFi light on your printer. If it goes to a solid green, that means you are connected back in your network. If not, you may reset your printer's wireless network adapter to its default settings. From the printer operator panel, press the Setup button > Network Setup > Reset Network Adapter to Default. The WiFi light on your printer will momentarily turn off then back on solid orange. Then try to run the Lexmark Wireless Setup Utility on your computer to reconfigure your printer to connect to your wireless network.I hope this helps.

The Z715 needs a #50 black ink cartridge and a working color cartridge to print. To check if there ios ink coming out of your black or color cartridge touch the bottom of it to a paper towel and if you see a solid black blob or 3 blobs of Yellow, blue and red for the color then your problem is else where. If U are printing stuff from the internet sometimes the printer will try to use the color cartridge to print this so even though the black is working it comes out blank if the color is dry
