Hi,
I am using dynamic web twain to scan document, but JS for it some times working and some times not working dynamicWebTwain1.AcquireImage(); method some times working and some times not working and also method is also some times working and and some times not working dynamicWebTwain1.attachEvent('OnPostAllTransfers', dynamicWebTwain1_OnPostAllTransfers);
below is code i am using
