SOURCE: Error message

Hi toolpusher

Try going to CanoScan Toolbox > Settings and reset the 'defaults' button at bottom... this will restore factory settings and hopefully fix your problem... The other error message you can expect to get is "unable to scan - insufficent memory, check your **** space' (or something similar)... same fix works for both! ...Have had both messages on mine, sounds like a semi-regular conflict on some sort, but seems to be easily fixed. Good luck :-)

SOURCE: when i try to scan

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

My canoscan fb620u shows device offline.


It your using a newer windows you probably need new software. Try Vue Scan it worked for me on Windows 7 64bit and I have the same scanner. With out dated software it wont recognize the scanner. Hope it helps

Canoscan Lide 60 suddenly cannot be communicated.


hi um i don't know if this will actually work but it did for me, I had 2 problems with the lide 60 scanner-one was a connection/cable thing and another was this "TWAIN source thing" and after installing this:

i seem to only have one....i think the connection/cable got fixed.
oh well, give it a try anyway :) cant hurt

Unable to select TWAIN source


tried uninstallin and installin canon scanner drivers..nothing works..still seeing unable to select twian source..

so i tried an alternative..here we go..
on vista 64 os/vista any version..click Start>All programs>Windows fax and scan

next click new scan on top and that got me going.

some say there are issues with the way usb talks to old scanners with new operating systems like mine (vista 64). hope it helps until you find the actual cure.

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.
