The method of enabling Canon logging has changed for the CR-120/150. This method will not work on any other Canon scanners.
In order to capture logs on these scanners, you need to enable an option in the Ranger Canon-CR120CR150.ini file.
You can find this file at this location:
C:\ProgramData\Silver Bullet Technology\Ranger\Scanner Plug-ins\Canon-CR120CR150\Canon-CR120CR150.ini
