Question : Problem: Cannot communicate with scanner

    I have contacted Canon Tech Support and Microsoft Tech Support.  Neither was able to help me solve my problem which is the scanner on the Canon MP830 will no longer work-it will not communicate with my PC.  I actually have 2 problems but don't know if they are related.  Recently I started getting notifications that Windows needed to install drivers for a Microsoft WPD FileSystem Volume Driver.  Today when I needed to use the scan function of my MP830, it wouldn't work:  Cannot communicate with scanner.  In the Device Manager the Microsoft WPD FileSystem Volume Driver has a yellow exclamation point by it and nothing I have done at the instructions of both Microsoft and Canon have been able to fix it.  Uninstalled device-rebooted-yellow exclamation point still there.  Completely removed all of Canon MP830 software and drivers and then reinstalled-no success.  Tried a shorter USB cable-no luck.  Uninstalled and reinstalled Canon drivers-no success.  I am at my wit's end on this problem.  Any help would be appreciated.  Thanks

Answer : Problem: Cannot communicate with scanner

My problem was solved indirectly when I was advised to reinstall Vista in connection with another problem I was having.  Please close this question.
