    Canon responded with continued disinterest in developing a Vista driver. Guess I'm stuck with my XP desktop to use the scanner until MS responds to the error messages I've sent. I continue to update my Vista as well. Thanks for the help.

    Same thing here...just because they make a good product doesn't mean they should abandon it. support it by making a vista driver!

This work around worked for me...
Install the XP Drivers on an XP Machine.
It will install to: C/temp/CanoScanCSUv571a
Copy that folder to a removable media
Paste the folder to C/temp/CanoScanCSUv571a on the Vista Machine

Worked for me...Good Luck.

You need the disk that comes with the Canon N656U scanner.

Connect the Scanner to the computer, plug it in and then connect the scanner to the computer with a USB cable.

Vista will then ask to search for driver software, hit "Search Windows Update, Let windows find software"... It will not locate software and then will ask for cd.

Insert CD into CD rom and Scanner will be installed.

Hope this helps!

You could try a 'forced install' of the XP driver. Plug in the scanner and when it asks for drivers point it to the directory (or CD-ROM) where you have the XP drivers stored. You can likely download the XP drivers from Canon's website. Essentially you tell the installation wizard that you want to show it where the drivers are that it should be using.

Alternately, I also know that Vista sends a log of unsupported devices to Microsoft. These logs are used by hardware vendors (and even Microsoft itself) to determine the value of writing a Vista driver. If you don't want to mess with Vista drivers you could plug in the scanner and let the installation wizard 'fail' and report that failure to MS. Keep checking Windows update and you may be pleasantly surprised to find compatible drivers show up one day.

Sorry that the second part doesn't actually solve your scanning needs today. For that you may have to actually buy a new scanner that's compatible with Vista. Bummer.

For others that are worried about this be sure to run the free Vista upgrade guide program on your current computer before upgrading to Vista. It will tell you if any of your hardware or applications are incompatible with Vista before you upgrade. This is available as a free download from

Plustek Optipro 9636T - working under Windows 7.

If you scanner only has Win XP drivers, then you have only two choices as those drivers wont work on WIN 7. One is to buy a new scanner, as you have already suggested. The other is to create a virtual machine, load WIN XP onto it, and then install the scanner drivers on the virtual machine. This should work fine as I do it for a piece of software that only works on WIN XP, however it is a bit of a inconvenience to use.

My Canoscan lide 700f will no longer scan negatives

Hello try to reinstall the software for the scanner from here:

Please select your windows system 32 or 64 bit.
Download the driver and uninstall the old software before you install the new.

Canon does make an driver upgrade once a while to fix previous problems with the software.

Hope this will help you

I have installed HP PHoto and Imaging Softward for ScanJet 3570c 48 bit. Everytime I try to click on icons on the scanner, my computer shows an error message that there is a problem with connecting to the...

Does the same error occur if you launch a scan from the computer? What OS do you have? Vista only has a basic driver available and does not support the scanner buttons. (You can launch the scans from a number of options: third-party software, Windows Fax and Scan (new scan), Microsoft Paint (File > Import from Scanner or Camera > New Scan) and Windows Photo Gallery.)

If the error occurs when you launch the scan from the computer, try a new data cable and different USB ports. Try a direct USB connection if you use a hub. Then check your USB ports and the drivers for the USB. (For Windows, look in the Device Manager. Start > Control Panel > System > Device Manager (exact directions will depend on the OS).

The HP Photo and Imaging software requires you to set the default scan destinations in the software before you can use the buttons on the scanner (for those OS/driver versions that support the feature). Always open the software and scan from the computer to see what the defaults will be. Each version of HP's imaging software set up these buttons differently; the help option is useful. Try Scan > Scan settings to find where to set the color and black & white destinations.

I hope this helps. If you add a comment with your OS and whether the computer can launch a scan, I'll provide additional help if I can.

Scanner operates but only black scan appears

I have many years experience repairing Canon scanners so here is my suggestion for you.

If you try to scan in another peice of software is the image still black? Try using Microsoft paint to scan a document or picture in with. If you get a good image then the software your using to scan with needs to be corrected its probably a setting in the software.

If you scan with another piece of software like microsoft paint and the image is still black then my guess is that your imaging lens is defective on your scanner and will need to be replaced. If that is the case its probably cheaper to buy a new scanner then to have it replaced.

I hope this helps you out.

Hi Canon don't provide up-to-date drivers for this scanner any more so you will have to buy a copy of Hamrick Software's Vuescan
It works with almost every scanner in the world (seriously) but you have to buy it. I have no connection but have lots of cliens using it.

Canon 600lide scanner and Canon 350d eos xt digital camera

Isn't the "VistaScan" software designed for a Umax scanner?
It is probably proprietary software. If it is a Canon camera, it most likely came with something like ZoomBrowser.
