I'm not sure, but I think that no present Canon consumer level ink jet printers have rear feed trays for photo paper, at least not for A4/Letter size.
The newer Canon ink cartridges like PGI-x50/CLI-x51 are refill unfriendly, so third party cartridges with ARC chips are recommended. It seems the newest Canon cartridge generation is PGI-x70/CLI-x71. I don't know if compatible cartridges are available yet.
Instead of a Google search I suggest to check the Canon website of your country for specifications for different printers.
Thanks to PeterBJ who spent some time offering an honest answer.
As for the other two responders: I spent an entire week with Google to no avail. You shouldn't have butted in if you had no intelligent answer.
