Hello,

I am getting the following exception randomly while scanning, see stack trace:

(Data source is connected to maximum possible applications)
Stack Trace    at Leadtools.Twain.TwainException.CheckErrorCode(Int32 code)
   at Leadtools.Twain.TwainSession.StartNegotiation()
   at Leadtools.Twain.TwainSession.SelectSource(String sourceName)

I am using KODAK Scanner: i2000.

Any help on how to fix it would be appreciated.

Thanks.

Hello,
This error usually occurred when an application attempts to connect to a Source that only supports a specific number of connections when the source is already opened. This means if the scanner driver supports only one connection at a time, you cannot connect to the scanner driver using two or more applications at the same time.
Please make sure that there is no other applications are using the Data source (the Twain scanner), before connecting using your application.
