TWAIN UI not showing in C#

[TwainMan123]

I am using Twain in my c# application and have tested it on three scanners. One of these scanners does not show the twain UI when it is selected. The UI shows for a brief second and then disappears.

It has all the latest drivers/firmware. The scanner is the most expensive of the three, it’s sheet fed and able to scan both sides simultaneously.

Are there any know issues with UI like this?

Thanks !

Hi TwainMan123 – it is very unlikely that the UI of a TWAIN scanner does not work.
So most likely the problem is in the code in your application, that is controlling the scanner through the TWAIN API.
What is the code that you are using to talk to the scanner? Is it an open-source project, or a commercial library, or you wrote it from scratch?

And it’s OK to say the name and model of your scanner 8)
