Hi!
To ensure the most accurate information is provided, we will need to know the version of Mac you are using. Also, please double check the printer model. On the printer itself, you will see the model name such as PIXMA or imageCLASS followed by a series of letters and numbers. Which model do you have?
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://bit.ly/EmailCanon 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 and have a great day!
