Since version 6.3.1 of Dynamic Web TWAIN, we added a new property called "LogLevel" to catch detailed information when necessary. The property returns or sets the log level for debug purpose.

Data type: Short

Syntax: ObjectName. LogLevel

Remark:
0 - The default value for LogLevel.
1 - More output information will be provided for debug

Step-by-Step Usage Guide:

1. Add LogLevel property to your code as follows:

function Pageonload() {

    DynamicWebTwain1.LogLevel = 1; // please change DynamicWebTwain1 according to your setting
    ...
    ...
}

2. Download DebugView here, and unzip locally.

3. Run Dbgview.exe

4. Access your scan page, and reproduce the issue you are experiencing. The DebugView will record detailed information during the process, as shown below.



5. Please click on Save to save the log file and send it to Twainsupport@dynamsoft.com.

We will then check the files and give you a proper solution.
