I didnt, but I do now and now the scanner window just comes up blank
By default, the Scan Mode is set to Flatbed. If you don't have a document sitting on the platen glass, then you will get a blank scan. So either move the document to the platen glass or change the Scan Mode in Image Capture to Document Feeder.

With regards to MF Toolbox not working, you need to configure the application to use the networked MF. Open MF Toolbox and click on MF Toolbox and then select Network Scanner Settings...
From the next window that appears, click the plus button

The MF4890dw should appear in the Add Network Scanner list as shown below

If it does, click Add. The window above will close and return to the Network Scanner window and will now list the MF4800 Series as shown below. Quit this window.

The last step is to select Scanner from the MF Toolbox menu and select the MF4800 Series.

The MF Toolbox window will now appear and let you scan. Remember that you need to have Scan > Remote Scanner selected on the MF.
