Any paper jam while scanning causes the scanning executable to lock up until an End Task is performed. We are using 7.5.0. We call ImageEnIO.Acquire. Any time a jam occurs an AV is thrown inside the ImageEn units which appears to be handled but control is never returned so the program sits waiting for ImageEnIO.Acquire to return. We also do not get any further callbacks to the OnAcquireBitmap.

We did see in 7.0 a bug fix was listed:

ImageEn 7.0.0 (8 Apr. 2017) 
Bug Fixes 
Fixed: TImageEnMView.Acquire locks up when scanner jams


Our code:

    if not ImageEnIO.SelectAcquireSource([ieaTwain]) then
      Exit;

    ImageEnIO.TWainParams.PixelType.CurrentValue := Twain_PixelType_BW;
    ImageEnIO.TWainParams.VisibleDialog := False;
    ImageEnIO.TWainParams.BufferedTransfer := True;
    ImageEnIO.TWainParams.ProgressIndicators := False;
    ImageEnIO.TWainParams.AcquireFrameEnabled := False;
    ImageEnIO.TWainParams.DuplexEnabled := False;
    ImageEnIO.TWainParams.XResolution.CurrentValue := 300;
    ImageEnIO.TWainParams.YResolution.CurrentValue := 300;
    ImageEnIO.TWainParams.AppVersionInfo := '10.0.0.0';
    ImageEnIO.TWainParams.AppManufacturer := 'Abeo';
    ImageEnIO.TWainParams.AppProductfamily := 'Medical Imaging';
    ImageEnIO.TWainParams.AppProductName := 'MedSuite';
    ImageEnIO.TWainParams.FeederEnabled := True;
    ImageEnIO.TWainParams.AutoFeed := True;
    ImageEnIO.TWainParams.LogFile := c:\MedSuite\scan.log';
    ImageEnIO.OnAcquireBitmap := TwainDibCallNew;
    ImageEnIO.Acquire;
