PIXMA TR7820 How to change back to cassette feed

[WRK71]

Hi...I just purchased a Canon PIXMA TR7820 printer.  I changed the feed tray from cassette to rear feed to print a photo, and now cannot figure out how to set it back to cassette feed.  Would appreciate instructions on how to do that. Thanks!

Hi WRK71,

I can assist you with this issue.

What size and type of paper is now loaded?

Are you printing from Windows?
or Mac?

Hi...I am using 8.5x11 printer paper, and printing from a Mac. Thanks.
