Epson Perfection V100 photo scanner issues

Hi.
The driver software must be installed before connecting the scanner to computer, or installation may fail.
If you have plugged in USB before installing software, then remove the installation doing a system restore to one day before you installed the scanner. Reinstall the scanner afterward.

You find system restore at: Start>Programs>Accessories>System Tools>System restore.

• Chose one day before scanner installation, and restore to that day.
• After restore , restart computer keeping USB cable to scanner unplugged.
• Download all software and drivers here :Epson Perfection V100 Photo, Drivers & Downloads
• Install drivers starting from Twain Driver.
• Plug in USB only if asked by installer program
• Restart computer after installing, and plug Scanner USB if not done already on setup wizard request.
• Possibly use a different USB port, if you have a replacement USB cable also test it.
• Ensure that firewall and security software has been disable throughout the whole process.
• Ensure that you installed all scanner software. If you install Twain driver only the scanner will work, but you will need to use an external application to acquire scans.

If still no luck, then there may be a an issue with the recently re-released service pack three (SP3 is 3 yrs old). In that case you can uninstall SP3, reinstall drivers, and reinstall SP3 on top. There are device drivers that had not been tested on SP3, and sometimes this can cause installation troubles.

Best regards.
