Hi

The PIXMA driver for your device only provides USB, you need a recent 
version (this is not the case for ubuntu 18.04).
For the network it's a driver that uses the eSCl.
You have two possibilities:
1 put ajour sane;
https://launchpad.net/~rolfbensch/+archive/ubuntu/sane-git
> sudo add-apt-repository ppa:rolfbensch/sane-git
> sudo apt-get update
> sudo apt-get upgrade

Normally your device works in networks

2 Installing sane-airscane
