Autocrop in Brother DCP 120C

Hi,

Can anyone suggest how do I turn on autocropping in my Brother DCP 120C (MFC series). I am using
Scansoft Paperport SE 9.0 that came with the printer.
I have scanned auto cropped images before using the same setup but since I formatted my m/c the
autocrop won't turn on at all. I tried turning on the option in the printer setting but that didn't
work.

Would be awesome if anyone had any suggestions for me.

Thanks,
Ranjit
