I get a message saying the printer cannot communicate with computer. Everything is connected properly. Also, the wifi light is flashing. Sometimes it prints, but it randomly cannot "communicate" with the printer.

A quick fix for most communication errors can be achieved by resetting the printer and/or rebooting the PC. Simply disconnect the printer from your computer (if USB connected)> reboot your pc > unplug and re-plug the printer into the power source to reset it. When the printer turns on, reconnect it to your computer (if USB connected). Then try to print again once the computer fully recognizes the USB connection or when the WiFi light on the printer turns solid green (if WiFi connected.).

If that doesn't help, try the steps below:

1. Disconnect the USB cable connecting the printer from your computer.
2. On your computer, go to Control Panel > Printers and Faxes.
3. Delete the Lexmark print object.
4. Reboot computer.
5. Re-brick your printer by pulling out the power supply - black box where the power cord is plugged into on the back of the printer, and re-plug after 30 seconds.
6. When the printer turns on, reconnect it to the computer.
7. Wait until your computer fully recognizes the USB connection. To check, go to Control Panel > Printers and Faxes. If you see a new Lexmark print object in the list, try to print a document to verify that the problem is fixed.

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 flashing status of the WiFi light on the printer indicates that it's either trying to connect to a wireless network or it has gotten disconnected from your wireless network.

The flashing light indicates that the printer is either trying to connect to a wireless network, a "connection failure" or a communication is not available.

Couple of things to consider and try,,,have you tried another USB device in the computer, like a flash drive? If it can read the flash drive ok then the problem is not the USB port. Try using a different USB cable for the printer. Make sure your computer is up to date with the most current drivers. To me it sounds like a bad printer cable. Another thing to try is having the printer attached and when the error message comes up try wiggling the cable to see if communication is restored. If so then chances are that the printer cable is bad. Hope this helps.

Make sure the wireless LAN of your computer is set to AdHoc mode if the Printer is set to that function.

If the start button light is flashing red, it is because of one of the following problems:

• The scanner is not connected to your computer properly or your software is not fully installed.
• The transportation lock is locked. Slide the lock to the unlock position.
