Hello - I'm having the same issue where my Scanner just stopped working. "Scanner Utility" is greyed out under "WINDOW" which is odd. However, I never used that before, when I went to the Canon MG6300 application, I would see an "Open Scanner" tab an I no longer see this.
I've reset the printer, I've tried it with both Wifi and wired Ethernet cable. I've checked the firmware and it's up to date. I'm not able to download any official driver from the Canon website, presumably because the drive is on my 2016 macbook pro.
I'm on Monterrey 12.7.2 and i'm not sure if that is the issue.
Regardless, of the software and drivers I could download, I downloaded IJ Network Tool, My Image Garden and Quick Menu and nothing gives me any sort of hint at a scanner...Plus, I never had to download any of these in the past. It was just always in the Canon MG6300 application.
HELP!
Thanks,
Mark
