Sometimes I manage to get things working by replugging the USB-cable and switching the scanner OFF and back ON, but that solution doesn’t last…Įven though Canon does not list support for your the CanoScan 5600F for macOS 10.15 Catalina, the Canon driver that used to work in MacOSX 10.7 Lion through macOS 10.14 Mojave still works in macOS 10.15 Catalina, so if you do not have this driver already, download it here The exact error message is this : “ Scanner reported an error Cannot communicate with scanner for these reasons: – Scanner is turned off.
However : now, in macOS 10.15 Catalina I keep getting error messages that the scanner cannot be found… I have been using my Canon CanoScan 5600F scanner for many years with my Mac, and it has always been working great.
