The Twain source is the Picture or Photo program First I do not think your Scanner will run on XP because i have one and i have tried the original drivers Second I got my scanner running on an old computer with Win 2000 and had to use two sets of drivers FB330P/FB630P & FB630U/Fb636V then I open MS Photo editor and Click on FILE then go down to select source and click on the second entry of the scanner the go FILE Scan Image If you not not have MS Photo editor it may work with other programs

AFTER LOADING SOFTWARE I COMPLETED THE TEST, IT THAT OK BUT WHEN I TRY TO SCAN, PRINT COPY OR ANYHING IT TELLS ME UNABLE TO CONNECT TWAIN SOURCE


Hello.

Give this a try (found online):

Download Irfanview:

http://download.cnet.com/IrfanView/3000-2192_4-10021962.html

Open the main app "i_view32.exe"

With the scanner hooked up, click onto the "file" (tab)

Click "Select TWAIN Source .." and select your scanner in the source box (if it is listed, the driver is functioning)

Click file (tab) then "Acquire"


Hope this helps.

When i try to scan i get this message: unable to open TWAIN source Please check connection then re-start Toolbox the connections are tight


Driver mismatch - the driver of the scanner has forgotten the location of the TWAIN driver because another software has been using it lately. Follow this

When i am going to scan at that time in the screen select the twin source. what is the twin source of canon canoscanlide25


Hello,

The prompt is probably asking you for the TWAIN source to use. In that box, simply select the Canon TWAIN source. If one isn't present, install the TWAIN drivers for this scanner.

Hope that helps,

Genius and Vista


There are two common ways to software-connect scanners
to windows:

1) The TWAIN driver interface
2) The WIA (Windows image acquisition) driver interface

===========================================
WIA is a driver interface native to Windows:
http://en.wikipedia.org/wiki/Windows_Image_Acquisition

TWAIN is a driver interface specific to each scanner
===========================================

Most new scanners should support both driver interfaces !

TWAIN is preferable, if you can find it, because it is tightly
coupled to the scanner's hardware design, and therefore offers
more functionality, which is hardware specific.

WIA, on the other hand, is more generic.
It will work with many different scanners, but with reduced
functionality, especially in the tools and setting available within
the scanner control window that pops up every time you try to
scan a document from within an application.

If you cannot find TWAIN, you may have to settle for WIA.
(if it will run with your hardware)
=====

This biggest problem, of course, is VISTA itself, and it comes
in two flavors, depending on your computer CPU:
64-bit and 32 bit.

64-Bit Vista drivers are the hardest to find.
32-Bit Vista is a DOG, because the software is too bloated
to run on a 32 bit machine.

Fancy colors and GUI not withstanding, 100% of the added
"new functionality" within Vista is for the benefit of Microsoft
and the scumbags running Hollywood. Vista hi-jacks your
expensive hardware resources and slows down "YOUR"
machine at "YOUR" expense to promote Microsoft's
insestuous relationship with the Sony movie studios and
the RIAA.

I strongly recommend to all my clients to stick with XP for
now, and avoid Vista like the plague.

I do !

Your post for CanoScan LiDE 25


Hi there, yes I did everything per your instructions, Toolbox is installed and it still says, "release the lock switch, detach I/F cable and reconnect. Scanner driver will be closed" and then after clicking on that it says "Unable to open TWAIN source. Please check connection then restart toolbox" I have been to the Canon site and downloaded driver sites and it says everything is working. but when I go to scan it comes up with the boxes I said before. Quite lost at the moment? Thanks Maureen. PS I have unstalled and reinstalled

Lock Switch and IF cable


Mine was doing the same thing. When I get on the program, before I click "acquire" to preview and scan, I click OFF the toolbox and then everything seems to be okay and I can go ahead and scan.
