I have a Workcentre 6505N connected to my private network.
I can print from windows, and osx (all machines have drivers installed).
I can scan from windows machines but i can not scan from osx!
I installed the latest drivers but the scanner is not available.
As you can see, in the top of the page there's the "important" sections saying that you must connect the 6505 to your mac using a USB cable!
I have the 6505 connected to my private network so no direct usb connection.
