Need Twain driver for windows 7 for canon Scan N12400 flatbeb


The TWAIN drive should be installed when one installs the actual "Drivers" for the unit itself, accordingly I provide you with the download link below.... look for and install ALL drivers and software, especially the Scan manager and TWAIN drivers....

Keeps saying "scanner failure" What do I do?


Scanners are a real legacy issue within windows - they have been there forever and yet the software controlling them hasn't been improved on - TWAIN it is the name of the Toolkit which communicates with your scanner and the proprietary software sits on top of that. TWAIN stands for "Toolkit Without An Interesting Name" - I think says it all. It hasn't been improved on much through the various releases of Windows. But to help you more we would need a lot more information.

- Platform Windows 7 .... Mac ...
- Scanner name and manufacturer
- Type of connection to the scanner ( USB ¦ WIRELESS )
- Whether you have had the scanner working in the past on this machine.
- Does the scanner work on another machine - Do you have another machine on which to try the scanner.
- Do you have the original disks for the scanner. And the original Windows Disk - so that you can load up the TWAIN software.
- How did you install the software for the scanner
- Have you come across this TWAIN driver ( perhaps you haven't installed that - because the Manufacturer's software doesn't include the TWAIN driver ( you have to load that from your Windows disk )

If you haven't loaded the TWAIN software - then perhaps - you should de-install the Manufacturers software and then install the TWAIN driver from the disk ( although - it may already be resident in the bowls of the Windows environment on the machine ) and then finally re-install the Manufacturer's software ...

So more questions than answers - but I hope that helps ....

Will not dow load to vista it can not find twin


I think you mean TWAIN.

twain is a sub process that is used to make scanning easier between different applications.

Part of what you want to do depends on the application you are using to scan your document eg word, photoshop, etc etc.

Quite often when you install the software for a scanner it will ask if you want to install the twain components. You should click yes.

I would try to re-install the software for the scanner including any updated drivers from cannon support on the web.

Some applications may offer other methods besides twain to get yoyr scan. If you select one of those and try again.

Hope this helps

I have installed the UE 404090, but cannot scan to my PC. It says no twain compliant found. If I press scan/file on the machine it says select destination _ what can I do there?


Hi,

Have you at some point installed a second scanning device on the system..

Reason being TWAIN is configured slightly different by every manufacturer to optomise the working of their hardware.

It some cases when you install a TWAIN device for Scanner A this can interfere with Scanner B
Usually its because your trying to use TWAIN(scanner A) on Scanner B

Make sense?

Make sure (if you have installed another scanner device) that you are using the TWAIN software that came with .

You might need to reinstall the entire set up from beginning.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

I have a Canon scanner 5000f. All of a sudden the computer won't recognize it and says it is "unable to select Twain Source." What do I do?


First you need to follow the instructions for installing the scanner. It is important whether you connect the scanner before the software is installed and whether you work from the new hardware found box or just install the driver as software. It sometimes varies between operating systems as well.

Sometimes the twain files can become corrupted. Since other devices like digital cameras use the twain files they aren’t erased with a driver uninstall or overwritten with an install. If the twain files are gone the driver install will also install them.

Uninstall ScanGear (I think that is the Canon driver software) and remove the scanner if it is still showing in device manager and control panel under scanners. Unplug the USB.
Do a search for twain and delete all you find in the Windows folder. There is probably a folder and several files – delete them all. Do not remove any twain files not in the Windows folder.
Dig out the instructions and reinstall the scanner exactly according to them.

Downloading software (Twain??)


The download website for your scanner is here:

http://www.usa.canon.com/consumer/controller?act=ModelInfoAct&tabact=DownloadDetailTabAct&fcategoryid=351&modelid=8008

A TWAIN driver is simply a generic scanner software driver that your specific Canon software can hook into and use.

I recommend starting with this one and see if it installs the TWAIN driver you need:

"CanoScan Toolbox v2.2.3 for Windows 98/Me/2000/XP"
