So we just picked up a Canon PIXMA MG7520 and it found a driver in the 7500 series and it prints fine. However, we went to scan via wifi in ImageCapture. It sees the device under "Shared", but when you click on it, it says it doesn't have a driver. Anyone get this working or are we just waiting for the next update of drivers or 10.10 from apple to add in the scanner on this all in one printer?
