PIXMA TR4722 error code 1651 after replacing ink, won't print from iPad

[Firespooks]

I have a Cannon TR4722 printer. I recently changed out the ink cartridges. They were sent to me by Cannon directly. Now I keep getting the code 1651 and the message, printer  cannot communicate with the ink cartridges.  My printer is on line. Any ideas? Thank you , Stephen Casper.
