I am trying track down a possible bug in AC. My canon dr-2050c and dr-2010c both can only scan to the 2 greyscale settings when controlled from AC and creating PDF's. Does anyone else have a canon that also has this problem?

I can't be certain if this is the Canon or AC, if someone else has noticed this then it may be AC.

Greyscale takes up 2-3 times more space than B&W so this is an issue. Our imported items folder is already up to 1.59 GB.
