After much trial and error I can report the successful setup of the Canon PIXMA MX-922 All-In-One scanner on network/wifi. I wanted to share my success with everyone. This assumes the printer portion is already working. 3/30/2018
1. Firewall, by default, blocks most incoming requests. To allow scanner traffic add 'Scanner' both directions on port 8612. You can shut off the Firewall temporarily to get it set up and working.
Ref: https://www.systutorials.com/docs/li.../5-sane-pixma/
2. Terminal: "sane-find-scanner" command shows only SCSI, USB and parallel-port scanners. No network printers will show up using this command!
3. Terminal: "scanimage -L" command returns, device `pixma:MX920_192.168.0.30' is a CANON Canon PIXMA MX920 Series multi-function peripheral (at least mine does since installing the Canon printer). Best to assign a static IP address since DHCP can reassign addresses.
4. Using software center/package manager add 'sane' scanner graphical "backend." Also add sane-utils and libsane-extras.
Terminal: sudo apt install sane sane-utils libsane-extras
5. Add sane-git repository in order to receive updates:
Terminal: sudo add-apt-repository ppa:reolfbensch/sane-git
Terminal: sudo apt-get updates
6. Install a scanner "frontend" application such as Xsane, Simplescan or similar.
