Hello, VishalJani.
Once again, I repeat. Well, it means that the scanner will continue waiting for new pages for scanning. The Twain32.AcquireCompleted event occurs at the time of completion of the cycle of image scans. It can not be called manually. The initiator should be a scanner. The application can tell the scanner that does not need to scan more (if that makes sense). And then will be occurs the Twain32.AcquireCompleted event.
