What if my scanner doesn’t show in Firefox or Safari?

Due to different security strategies, Firefox and Safari won’t show some of the scanner sources including the Sample Data Source that you might have installed from Dynamic Web TWAIN online demo page. When this happens, you will see more sources in

than in Firefox/Safari:

To resolve the issue, you can:

  1. Go to the folder of the sources (Normally @ “%Windows%\twain_32”).
  2. Find the folder for the missing source.
  3. Open this folder and copy all files to %Windows%\System32 (or %Windows%\SysWOW64 on 64-bit OS).

After that, you can refresh the page to see the available sources on your machine.
