Does anyone know of a Lexmark X74/75 All-in-one Driver for Vista?

Hi Colleagues,

I have a legacy Lexmark X75/75 All-In-One for which I cannot locate a VISTA O.S. Driver. The LEXMARK Web Site seems to be too flaky to get me to the Lexmark Tech Support page and so I wish to get some assistance or advice elsewhere. I just found this site today and thought I would see if I could find help here. All recommendations/suggestions are welcome. Many thanks, I will listen out for any responders... Thom
