ntwain v3 how to check if transfer completed

[jamokop]

i can scan paper successfully , now i want to call a function after scanning all the papers. however i can not find an event which will be triggered after completion. any suggestion?

You can try the SourceDisabled event. Though you'll need to keep track if pages were scanned yourself.
