SOURCE: I'm getting 2 error messages

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

This is a common problem with all Canon scanners. If you do a lot of scanning or leave your computer on all the time and never shut it off. What is happening is the memory fills up with all of the images and it needs to be cleaned out. If you reboot (restart) your computer it will clean out the memory and your problem will go away. I always recommend that if your going to be scanning a lot then do it off a fresh reboot and you should be able to your hearts content.

I hope this helps you out.

Hello.

Give this a try (found online):

Download Irfanview:

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

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.

Scanner problem


Check to see if you have the directory c:\windows\twain_32 with subfolder for your scanner.

Also check that you have the twain drivers in c:\windows\system32

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 !
