Scanner over network not detected - Canon G3111

I´m trying to use SANE to detect Canon G3111 (G3010 family) installed over network.

Printer works very well, but scanner is not detected by SANE. I tried all ways that I found in sane website, without sucess.

With ScanGear MP 3.70 scanner works very well, but only a single page by time.

I am willing to help SANE developers to make the operation compatible with this scanner. I don't know if this is the right place for this, but I am available for that.

I use Linux Mint 19.04 and POP! OS 20.04 and feel free to contact me.

Thanks for your support and best regards!
