Controls how a Canon scanner detects the page size when auto cropping is activated in the Scanner settings dialog (or by using CanonAutoCrop).
This setting may not work with all Canon scanner models, but it is recommended— together with ByteAlignment and UseMiniDriver— for models DR-3060, DR-3080C, DR-6080 and DR-9080C.
For models DR-3060 and DR-3080C, select Crop and Deskew in the ISIS scanner settings dialog to get cropping and deskewing to work.
For models DR-6080 and DR-9080C, select Crop and deselect Deskew in the ISIS scanner settings dialog to get cropping and deskewing to work.
Important: Canon model CR-180 does not work without ByteAlignment.
