MG8220 Won't print from rear tray

[seismic]

I've been printing from the rear tray forever. Suddenly my Mac was no longer seeing the printer so I reinstalled the printer software. Now the printer prints from the main tray even when I choose rear tray.

It just refuses to recongnize the rear tray.

Hi seismic,

What version of the macOS is installed on your computer?

What size and type of paper are you attempting to load in the Rear Tray?
