Hello!
So that the Community can help you better, we will need to know exactly what model printer you're using (it's usually on the top or front of the unit), any error messages you're seeing, and the Computer Operating System you're using (Windows Vista/7/8/10 or macOS 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 call 1-800-OK-CANON (800-652-2666) 8am to 8pm (ET) weekdays.
If you're outside of the USA, please click HERE to find support options in your country.
