Try unplugging it for 10 minutes. While unplugged, press and hold the start and stop but for 10 seconds. Double check for any paper jams. Just the smallest piece can jam it up. There should be a list of error codes for anything wrong. List paper jam would have an error code, change toner, change or clean ink, ect. Is this the only message you get? If that's so, try the steps I mentioned above so the machine resets itself. It the problem still occurs, let me know I will gladly help you to correct this problem.
