I went out and bought a canon mx300 multi function today. I got printing working OK, although I have to say I find it extremely annoying that the "print preview" in all applications doesn't reflect what I am about to print. For example if I set it to Greyscale in the options the preview still shows colour. Anyway, I just now tried to use the scanner. I put it on scan and hit the button and imagecapture opens up. It shows a preview of the scan and all the usual options. One problem, the "Scan" button is disabled. Why? I can't figure it out. Also in the options of ImageCapture I have set it to open "MP Navigator EX 1.0.app" as per the instructions, however that doesn't seem to be happening. I have installed the Canon Scangear software (presumably MP Navigator EX) but I can't find where it installs itself too so I can't open it in manually. It's definitely not in the Applications\Canon Utilities folder where it is supposed to be. (Yes I have tried reinstalling it. Does anyone have any suggestions on a. why I can't scan from ImageCapture (even though it scans it and shows the preview) or b. where Scangear installs itself too?
