I'm seeing the same thing on my macOS test system when I configure a C7000 printer with 2 trays. It seems like the bypass tray is counting as one of the trays, so I only see tray 1 and the bypass. If I change the printers installed options to show 3 paper trays then I have the option of printing to tray 2 available. Try the following and let us know if it works for you.
Open System Preferences
Click on Printers & Scanners
Click on your printer to select it
Click Options & Supplies...
In the new window that opens click Options
Set the option for Paper Trays: to 3 Trays
Now tray 2 should be selectable when you print.
For some reason I can no longer send A3 jobs (paper in Tray 2) to the printer.
Tray 2 is greyed out in the printer settings. It used to work ok, but I can't figure a way of enabling the second tray.
Latest Xerox print driver (5.6.0) installed. I'll be pathetically grateful for any help!
