Do u have the latest drivers? http://usa.canon.com/cusa/office/products/hardware/multifunction_printers_copiers/black_white_copiers/imagerunner_7105#DriversAndSoftware
I do not have a separate RIP like an imagepass controller. All of the Drivers in the link that you sent me are for printing. I don't see any Network Scangear applications there. I have drivers for scanning that work with my XP computers and the iR7105. They don't work with Windows 7 64 bit
