You are going to have to explain more than "Scanner not working", that could be anything from "It caught on fire and is a pile of melted plastic" to It works perfect but the file is a tiff instead of a pdf.
What errors? What are you doing? Does the driver install or not? Does the program run? Does the scanner initiate?
Please describe the issue because so far all I have had to work with has been that the driver won't install, and the next sentence was that when you install it , it doesn't work.
What OS, What error, What driver etc etc
