Hi,

I am confused. In order to scan the back of a page must I use
 source='ADF Duplex' 
or
duplex=''both'

I don't understand the difference between them. 

(My problem is that I am not able to get the back)

thanks

Which scanner backend are you using?

Typically you will specify a duplex source, then repeatedly call scanImage() until you get a SaneException with SANE_NO_DOCS as the status code, indicating no pages are left.
