Hey all.

I have a Canon LiDE 220 scanner connected via USB. It only returns a black image on previews and scans both with Skanlite and via the command line.

Scanimage -A shows it, Scanimage -T passes. The site shows it's supported by the genesys backend, which I have set in make.conf under SANE_BACKENDS and I "re" emerged the package. Even added my user to the groups it says to do in the wiki and did a full reboot. The genesys.conf file in /etc/sane.d/ has the right usb entry uncommented.

I have no idea what the issue is.

dreamLogic,

So you have done all the right things but it won't work. Maybe you have an error your can't see?

Show us

Code: Select all

so we can see the Vendor and Device ID of your scanner.
Post your genesys.conf file.

Show us that /etc/sane.d/dll.conf has genesys enabled.
