Why is my Canon scanner not appearing in Mac Settings? Hi please can someone help me? Bought myself Canon Pixma G3430 printer recently. Connected it via wi-fi, printing is working well and I see the printer in the "Printers and scanners" settings (I`ve added it here). But the "scan" section has completely dissapeared from the settings. Tried to install IJ Canon Scan Utility, but everytime I want to activate it, I have this error: "Cannot communicate with scanner for these reasons: - Scanner is turned off. - (If using Wired LAN connection) It is disconnected from Wired LAN. - (If using wireless LAN connection) Signal strength is poor due to obstructions. - Network connection is prohibited by security software. - Different scanner on the network is selected. Check the above and try scanning again. If you still cannot communicate, restart the computer." Downloaded Canon wi-fi connection assistant too and everything seems fine here. What can I do now? Thanks for every advice [Re-Titled by Moderator]

Please verify that you installed the latest driver software (and apps) for this Canon device, in case that they made accommodations in there to the latest version macOS.
