Hi there,

I am trying to automate sccanning a batch of document with a script in python using Pyinsane2. But when I Call the scan_session = device.scan(multiple=True) routine I get the mesage "Pyinsane: Stream::QueryInterface(): Unknown interface requested" several times, and the python and if i press enter it returns an empty scan_sessions.images, and doesn't proceed to the next sheet.

I am using python 3.6 in a Windows 10 with WIA2, the scanner is a Lexmark all-in-one Mx410de and the connection is over lan.

Any guesses on How to fix this? Thanks
