My new Canon Color ImageClass MF753Cdw prints fine wirelessly and it used to be fine with wireless scanning. Suddenly, my iMac 20,2 using macOS 15.0.1 does not detect my scanner. Any advice? I've tried all the usual.
iMac 27″, macOS 15.0
After having installed the software again I just thought about your first hint to look for Settings>Privacy & Security>Local Network. In fact the scanner was not enabled there. While it was not listed there before now it was. After enabling everything is fine. Thanks a lot!

Try looking in System Settings>Privacy & Security>Local Network and see if the device enabled. Some devices might have a update to their software on the vendors website for Sequoia, if it isn't working
Find out if there are any updated drivers for it from Canon
Well, you're a genius in my book. A humble genius. Again, thank you!
Did the upgrade to Sequoia surreptitiously turn the enabled button for the scanner off (under Privacy & Security/Local Network)? I'm just trying to figure out how my scanner suddenly stopped working but my printer (both on the same Canon device) continued to work fine.
You're a genius!!!!!!!!!! I can't thank you enough. Did Sequoia turn the enabled button for the device off? This is the first time I tried scanning since the upgrade to macOS 15. You are a lifesaver!
hello,
I have the same issue with an MF633/635 but I recently did not allow the search for any devices by the scanner utility when I was asked for.Assuming that my current device would still be known I did not expect any need to search for (more). Looking into the Local Network settings as described in this thread does not show any scanner at all. Printing still works fine. What can I do?
thanks upfront!
I just installed the latest printer software, restated the iMac but with no effect on the issue. Still the app does not find any scanner. Do you know where I can find the settings for the app 'digital pictures'?
Your Welcome. Not a genius, just a average Mac user.
