Found my answer a few minutes after my post.
I installed this driver : http://www.office.xerox.com/software-solutions/global-printer-driver/enus.html
And then, my other trays weren't detected. I just had to configure the printer settings to add two extra trays and now it works!
Hi,
I have recently bought a used Workcentre 7132 and I'm struggling to print from any other tray than the first one.
I couldn't find any driver for Windows 7 x64 so I had to install the driver for Windows Vista. It looks like it's not perfectly working.
When I try to print, I get an error message telling me tray 2 (or 3) isn't installed. Here's what I see when I want to select another tray (sorry, this is in French, but you can still see the little exclamation mark) :
Does anybody know how to fix it?
Thank you very much in advance!
