Why don't CR-180 gray scale images display in my application or the demo application?
It is possible that ceijpeg.dll is not installed correctly by the original Canon install package. This causes an issue on Windows when it tries to load the DLL from the Canon directory (instead of the Ranger directory).
A file size of 512 bytes is always returned if the DLL fails to load. Thus, grayscale imaging fails.
Solution: copy ceijpeg.dll from the Ranger install directory to the '\WinNT\System32' folder.
