Hi there. I'm running Mac OSX Snow Leopard. I have the unit plugged via USB into my Airport Express; I can print/copy fine but this item does not scan at all. Firstly, when I select "Scan to PC" on the unit, it says "Local PC" or "Network PC"...I've tried both, neither work. I've installed all the drivers and updates but I still can't scan. I've opened Image Capture as well as the "mac compatible" driver from the samsung website but I still can't scan. Help! Thanks!
