I have a 

Canon imageCLASS MF216n All-in-One Laser AirPrint Printer Copier Scanner Fax

Tried to scan a photo the other day and tried using the window on printer and when I hit scan it says select scan type.  I choose computer but it then says Connect the Computer.  It is connected.

Tried then using the Canon MF Tool BOx V 4.9 and the window pops up but nothing is accessible.  I have to go to task manager just to shut it down.

ANy thoughts or advice?
