STEP BY STEP INSTRUCTIONS

1) First you need xsane to be able to scan things at all.
sudo apt-get install xsane
2) Plug in your scanner by USB. Attempt to scan by typing scanimage. It won’t work, but you need to see the error message.
scanimage
[gt68xx] Couldn't open firmware file (`/usr/share/sane/gt68xx/PS1Dfw.usb'): No such file or directory
scanimage: open of device gt68xx:libusb:004:002 failed: Invalid argument
See that PS1Dfw.usb? You need to get that file from http://meier-geinitz.de/sane/gt68xx-backend/ but be aware that your computer might ask for a different file such as ps1fw.usb or ps1fw.usb. Whichever it is, find it on the page and click it to download.
3) Remove the redundant gt68xx file from SANE
sudo rm /usr/share/sane/gt68xx
4) Make a directory in SANE called gt68xx
sudo mkdir /usr/share/sane/gt68xx
5) Move the downloaded driver from DOWNLOADS into the new directory
sudo sudo mv ~/Downloads/PS1Dfw.usb /usr/share/sane/gt68xx
DONE!
TRY YOUR SCANNER!
