Using the Windows XP driver MAY work. However, the D646Uex is not officially supported in Windows Vista. There is apparently some functionality limitations that prevent it from being officially compatible.

Dear Sami Kotaich,

unfortunately your Cannon has not released drivers for vista for this product.

I can give you one suggestion; connect your scanner with vista PC and atleast let it try to install necessary USB drivers. once it has been done you will see message your hardware installed or there was a problem installing drivers for your hardware and it may not work properly.

now leave scanner connected and go in start menu- programs- accessories- paint

once you are in paint click on File Menu then From Scanners or Cameras. if it does recognize and you get scan wizard then you will be able to use your scanner on vista. but if it doesn't recognize then I am sorry you might need to get more authentic recommendation from Cannon support.

let me know does it work or not? or if any more questions, please do not hesitate to contact me.

Many Thanks.

AJoshi

Canon Flatbed scanner model D646U ex for Windows XP


Could be a problem with the cables themselves. Try a new set or different set of cables and see if this resolves the issue. Also make sure that you installed the correct version of the driver for your OS.
Should you still have difficulties, try a clean boot as explained below:

(Just replace "camera" in the procedure for scanner.)
