First........lets establish info of what you have an what you've done.
1. Is the scanner hooked up via your printer port or usb??
2. Is it just not detected and responding or no evidence of power?
3. Have you changed anything prior to it stopping??
First one must start with the connections.........
If its via the printer port, does your printer still work??
Does the unit appear to have power?? (some have fuses)
Did you make any changes in the bios or in windows to effect
the use of the scanner??
Is it showing up in controll panel??
Did you get detection after reinstalling the drivers??
Several good points to start with............
Keep posted with progress
