Twain is the driver for the scanner. Have you tried to remove the driver and install it again? In any case you don't have the drivers if you need them, here is the location for you to select your language, operating system and download.

In case of a problem or clarification, don't hesitate to post.

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

Can't copy or scan on canoscan lide 25


You need to install the software drivers You need BOTH programs installed on your PC, Toolbox & Scangear. Also use the driver remover first. Then unplug scanner, reboot, install Scangear first, and toolbox second, then reboot, when at desktop next time, plug in the Scanner. Hopefully it should be all good. Read the Help file. http://software.canon-europe.com/products/0010219.asp

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 :-)

CanoScan LiDE 50, error code:2,7,0


When you say the error occurs as soon as you press "Scan", is that the button on the scanner, or is it the Scan button inside of Toolbox or ScanGear?
If it is the one on the scanner, try accessing the driver through an application such as Toolbox. If you didn't download that when you got the driver, then go back to the Canon download page and download & install the CanoScan Toolbox. Once that's installed, lauch Toolbox from Start|All Programs|Canon|....look for Toolbox from here. Once you have Toolbox open, click the 'Save' option. Next, check the box that indicates to Use the scanner driver. Click the Scan button at the bottom. This should open ScanGear. Attempt to Preview scan.
