I have a Canon MF6500 all in one scanner installed via USB on a windows 7 desktop. The Canon works great except when I try to scan from the Canon toolbox application. I get an error that the scanner is not active or in use by another application. I am able to scan from Devices and Printers without a problem. Windows is taking control of the scanner and not allowing the Canon toolbox cannot access it.
I have turned off the Windows Scanning and Fax Feature but that did not help. I have removed and reinstalled several times with different configurations (scanner not connected or scanner connected).
Is there a way to allow the Canon software to access the scanner first, or turn off Windows scanning altogether? I have installed a number of Canon scanners in my IT career but I have never ran into this issue.
Thanks for the help!!
