Like LatiosXT asked: "Is this about the printer or an SSD?" Because some of your explanation was a little misleading.
I will assume it is about your printer and the scanner not working.
I doubt it is a firewall problem because you said the printer itself works fine but the scanner isn't working, so they are talking. Does the computer tell you when it can't complete a print job because there is no ink or paper in the printer? I would think yes, which again means they are talking.
Reformatting the SSD and re-installing everything is probably not recommended on the SSD. I would double check to make sure the drivers you are using are the ones recommended for your OS, hopefully though Canon already ensured that, but just in case.....
I would uninstall the printer completely (drivers and everything), then plug it back into your computer and let windows see if it can find the best compatible drivers then see if it works. If still a no go I would give it a few minutes and check to see if windows update can find any updates for your system. If that still doesn't work you may need to give us a little more detail.
