Can I scan wirelessly to a PC, or do I need a direct USB connection? (MF6160dw)

[pacificdiver]

I'm using an MF6160dw on a Windows 7 machine.  The unit is USB connected to the main office PC, and I have 3 other machines set up to print wirelessly.  I can scan to the main office PC, but can I also scan to another machine in the office, wirelessly?  Seems like it should be possible, but I can't find any documentation on it.  

thanks
