[sane-devel] Problem with new Canon iSensys MF746Cx

Hi Alexander,

thank you for your reply. That did work indeed: the scanner gets
recognised as 'airscan:e0:Canon MF745C/746C'. However the list of
options for that device is very short. For instance there is no
"brightness", which would be very helpful when scanning a page printed
on the backside too. That's what I always have to adjust with the Epson
scanner in order not to see the back printing through.

In addition I just checked in my laptop, which has Ubuntu 20.04
installed instead. That has recognised the scanner automatically with
the "escl" backend. I don't see an "escl.conf" in my desktop with 18.04.
Is this just a matter of sane-version?

Is there any way to activate other functions for the scanner?

Thank you and regards,
