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.

Hello Charmaine,

Sorry to tell you but your scanner is not compatible with Windows 7. It only supports Windows 98, 2000, ME and Windows XP.

Hi jurjenweerma
There is no direct solution .
You need to use Windows XP or install a virtual version of XP on your pc .

If the Canon WEB site does not have the Windows 7 printer driver for your model printer then Canon considers this printer too old to support or it is not compatible with Windows 7 and they want you to upgrade your printer.
You can download the Canon printer drivers from theirsupport WEB site. Please click on this link and select your model printer todownload : - http://www.usa.canon.com/consumer/controller?act=DownloadIndexAct
