The link in the booklet is http://ij.start.canon (no dot com or anything else - there is no additional link provided once you get there - it takes you exactly where you need to be). IJ is for inkjet. start.canon isn't a valid site. The Getting Started booklet goes out to the whole world and does not include a phone number - because it would inundate phone support for simple requests that can be completed online.
The long way to find the number is here: https://www.usa.canon.com/contact-us/support
Once you're there, scroll down. You'll see a big red button that says "CLICK HERE FOR SUPPORT NUMBERS BY GROUP" - click on that to expand the list. Once you're there, you'll see that the most common number is 800-652-2666. For PIXMA Printers, you must have a My Canon Account before calling (that's why it says to check your My Canon Account first). The main number is still the same - 800-652-2666. But you must register first. That's at canon.us/account or https://myprofile.americas.canon.com/us/signin. Once you've done that, you'll see your support entitlements. If you're out of warranty, the most support will cost is $19.99, and you must pay that fee before calling. Our support agents do not take credit card information over the phone for support.
If they're going to initiate a remote support session, they do so with your permission while you're on the phone with them and while you're watching. You can see everything they do while doing it, and they usually explain what they're doing and why. This is not only for transparency, but they're teaching you how to fix the problem if you run into a similar problem later on.
I hope this helps!
