"Import from Scanner" greyed out in Preview app I have a Canon Pixma MG6300 printer/scanner for which I properly installed the drivers.

I know it is supposed to show in the Preview app under File &gt; Import from Scanner. This menu item, however, is greyed out.


Does anyone know how I can have my scanner show up in here?

Running on OS X Yosemite.
You can try below steps:


In System Preference > Printers &amp; Scanners, press Control and click the printer and click Reset Printing System.  This will remove all your printers.
Go to Utilities and open Disk Utility.  Click Macintosh HD in the left panel and then click Repair Disc Permissions in the right panel.
Restart your computer.
Re-install your printer.
