Try installing these drivers from Canon's site here.
All there is there are addon drivers. Which indicates internal drivers are supplied for the i6500.
Yeah you are right and it does not look like Canon had much other support for that printer. What you could try is to go into device manager (right click my computer/properties/device manager) and uninstall the printer drivers. Then reboot the computer and the computer should reinstall the drivers for you, or should at least ask to search online for drivers. If you do not get the prompt for the drivers you may need to unplug the printer then plug it back in and then the computer should do its thing with the drivers.
