We have an XP Pro PC connected to a Canon MF8180c printer via usb. Everything works just fine except for the scanner which displays a message saying that it cannot communicate and busy because another application is using it.
On device manager there is a yellow mark on it stating that windows cannot load drivers for it (CODE 31). I tried uninstalling and reinstalling updated drivers but the same issue persisted. I looked up the code and most articles on it suggested that I look up class upper and lower filters in registry for the device and delete them and that all should be fine for a reboot, so I looked up imaging devices filters delete them but it was no use.
How to fix that one with out formatting the pc?
