To disable logging to the Canon.log file:
- Ensure you are using Ranger for CR-180 v1.5.0.3 or newer (available here https://www.usa.canon.com/support/p/imageformula-cr-180-check-transport)
- Disable Canon driver support for Canon.LOG by ensuring that the registry key:
- HKEY_CURRENT_USER\Software\Canon Electronics Inc.\Canon Scanner Driver\Canon CR-180\General\Trace Log = 0.
Or if you'd prefer, just download the attached TraceOff.zip file, then extract and execute the embedded TraceOff.reg file.
