How to use TWACKER to check if your device is TWAIN Compliant?

  • [Recommended] Use the tool called Twacker which is developed by the TWAIN Working Group

    • Download and install

      Please download the version of TWACKER that matches your driver architecture, not your operating system architecture. In most cases, this will be 32-bit.

    • Open the program


  • Select your device


If your device is not listed, please check if the driver is installed. Or, try running Twacker as admin to see if it shows up.

  • Choose the settings and click the Acquire to start scanning


If scanning is successful without any errors, then your device should be TWAIN compliant. You can also try other commands to see how it works. If your scanner doesn’t work with TWACKER , please check your scanner model online and make sure you have installed the (latest) TWAIN driver from its manufacturer.


This list is maintained by hardware vendors and may be incomplete. In this case, try the two ways above instead.
