Hi, hermannj!
So that the Community can help you better, we will need more information on the problem you're having with your printer. Please let us know exactly which operating system is running on your computer, which applications you're using, and what settings, if any, may have changed between before and after the problem presented itself. That, and any other details you'd like to give will help the Community better understand your issue!
If this is a time-sensitive matter, our US-based technical support team is ready to help 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 and have a great day!
