I am running a MacBookPro, OS10.5.8. I have a Canon MX870 Multifunction Printer/Scanner hooked directly (USB) to my computer. I have the latest Canon software for this Canon. Using the Canon software it works perfectly in all modes. I on occasion like to use VueScan. Recently when I tried to use VueScan I get a message "No scanner driver found". I have reinstalled the Canon software and installed the latest VueScan software several times but still get the same message. I know the driver is there as I can use it when using the Canon software. Any ideas out there? Thanks.
