Windows 7 Win 7 Printer Dev Driver Issue

I've done all that. Did not find anything that would allow me to enable tray 2 in the print driver. This is what the "help" file says:

[TABLE="class: Block, width: 100%"]
[TR]
[TD]2
[/TD]
[TD]Right-click the printer icon,
and then click Properties, Document Defaults, or Printing
Preferences.
[/TD]
[/TR]
[/TABLE]

[TABLE="class: Block, width: 100%"]
[TR]
[TD]3
[/TD]
[TD]Select one of these tabs:
Configure, Device Settings, or Device Options. (The name of
the tab depends on the print driver and the operating system.) On the selected
tab, click the accessory that you want to turn on, click Installed from
the drop-down menu, and then click OK
[/TD]
[/TR]
[/TABLE]

I could find no tap that allowed me to "turn on" an accessory. Yikes!

So I poked around in the menu on the little touch screen on the printer, and found an icon shaped like a wrench (tools?). Clicked on it and then scrolled down to "preferences" and then "default tray" -- there I selected Tray 2. Powered the printer down and restarted it, and the setting remained. So I tested it and it seems to work. I'm not sure what will happen when Tray 2 runs out of paper (will it automatically revert to Tray 1?), but we'll see.

For now, I'm assuming that the problem is solved.
