Hi, jja!
Welcome to the Canon Forums and thanks for your post!
To have a better understanding of your issue, please let everyone know the printer model you have, what operating system (Windows Vista/7/8 or Mac OS 10.X) you are using and if you are connected via USB or WI-FI. Also, is the error occurring on the printer directly or from your computer? What is the exact wording?
If this is a time-sensitive matter, our US-based technical support team is standing by, ready to help 24/7 via Email at http://bitly.com/CanonEmail or by phone at 1-800-OK-CANON (1-800-652-2666) weekdays between 10 AM and 10 PM ET (7 AM to 7 PM PT).
Thanks!
