HP 4050N - Won't pull from manual feed tray

> Hello,
>
> I have an HP 4050N connected to my network, one user that
> uses this printer is having problems printing from the
> manual feed tray (tray 1 - Manual). And its only from
> that one computer...
> I've given the user account permission to manage that
> printer, but it hasn't helped. I've tried to select all
> the different trays, and it always prints from Tray 2.
> Everyone else can print from whichever tray they want...
>
> Any suggestions would be great!!!
> Thanks!
