Hello, I've got an MF4890dw set up and printing wirelessly on my Windows 7 system, but I cannot get the scan function set up. When I click on the MF toolbox, I get a message "A supported scanner is not installed. Please install a supported scanner then restart Toolbox" I cannot find anything about installing the scan function of this machine in the various manuals or Canon's online help pages. Any suggestions? Thanks in advance.
