I get this message: and the SN is correct, I verified it's correct on the outside and in the software
The serial number you have entered is invalid for one or more of the following reasons:
1) The serial number does not match the product you have selected (FCC ID which starts with "AZD" is often mistaken for serial number.)
2) The serial number entered indicates this product was not intended for sale in the United States and is ineligible for registration and support in the U.S.
Please verify your product model and serial number to ensure they were entered correctly.

Thanks so much for the info, Gilbert! If you need help getting your printer set up, it might be easiest to simply give our PIXMA support team a call. You can reach them Monday through Friday at 1-800-OK-CANON (1-800-652-2666). They'll be glad to walk you through the set up and help you with anything that might come up.
We look forward to your call!

The4 serial is correct, i have read it 5 times TR4729 canon printer

And it has matched each time you've typed it. Please make sure you get the model number right as your printer is the PIXMA TR4720. When you call and our automated operator asks you to state your model number, say it as "PIXMA T-R Forty-Seven Twenty." Our computer likes it when you say it that way. 😊
