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
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?
