Thank you for your recent enquiry regarding your Canon product.
In response to your query, please find below a step-by-step guide to follow in order to solve your problem.
This problem is caused by other twain drivers, which are installed on your System. (Former scanner or digital camera)
- Download the "Scanner uninstaller utility" from click here under "Download Software", "Scanners", select (name scanner). Choose your Operating System, language and the uninstaller utility. Create a folder on your C:\ and save and unzip it there. It will be easier to locate. - Disconnect the scanner from the PC during the uninstalling procedure. - Go to the folder containing the unzipped file. - Use the file "DELDRV", select your scanner and the *.inf file will be deleted automatically. - Go to the device manager; check if the scanner is still listed under "Imaging Devices". If so, delete it. - Go to the folder C:\Windows or WinNT and locate the folder "Twain32". Delete it completely. - Search for the folder "Twain_32" and delete all Canon-entries in this folder. - Search for the file "Twain_32.dll" (mostly shown as "Twain_32") and delete it. - Reboot the PC. - Connect the scanner to the PC again. - New hardware should be found. - Re-install the driver and use the installation path: CD-ROM drive:\ScanGear\English
