Hi STUMP!
Welcome to the Canon Forums and thanks for your inquiry!
So that the Community can help you better, we will need to know exactly what Canon equipment you're using, any error messages you're seeing (on the device or your computer), and the Computer Operating System you're using (Windows XP/Vista/7/8 or Mac 10.x), as well as the way you connect to your device (USB or networked via WiFi or Ethernet).
Any other details you'd like to give will only help the Community better understand your issue!
If this is an urgent support need, please CLICK HERE to reach our friendly Technical Support Team during normal business hours.
Thanks and have a great day!
