Canoscan windows 7 driver

TWAIN driver for the LIDE 20 doesn't exist. Canon does not support Windows 7 on that model.

You may to try VueScan software instead. It installs a generic driver which works for most USB scanners, but it does not include a TWAIN driver.

This means you cannot invoke the scanner from within an image-editing application, but you will be able to use your scanner with VueScan and save the scan as a JPEG file. Go here: http://hamrick.com
