我有下面的代码可以扫描所有纸张。它可以工作，但问题是所有论文都将完成时，显示错误：

  

用户未经处理的异常System.runtime.InterpService.COMEException：来自HRESULT：0 * 80210003的异常

属于此行：

var imgFile = (ImageFile)ScanerItem.Transfer();

我该如何解决？ 这是代码：

        public async void button1_Click(object sender,EventArgs e)
        {

                try
                {

                    object[] items = await Task.Run<object[]>(() =>
                    {

                        var deviceManager = new DeviceManager();
                        List<object> result = new List<object>();


                        for (int i = 1; i <= deviceManager.DeviceInfos.Count; i++) // Loop Through the get List Of Devices.
                        {
                            if (deviceManager.DeviceInfos[i].Type != WiaDeviceType.ScannerDeviceType) // Skip device If it is not a scanner
                            {
                                continue;
                            }
                            //new
                            result.Add(deviceManager.DeviceInfos[i].Properties["Name"].get_Value());
                        }
                        return result.ToArray();


                    });

                    foreach (var item in items)
                    {
                        lstListOfScanner.Items.Add(item);
                    }

            }
                catch (COMException ex)
                {
                    MessageBox.Show(ex.Message);
                }    
bool continueScanning2 = true;
    try
    {
        await Task.Run(() =>
        {
            var deviceManager = new DeviceManager();
            DeviceInfo AvailableScanner = null;
            while (continueScanning2)
            {

                string name2 = Guid.NewGuid().ToString().Replace("-","") + ".jpg";
                var Path = @"C:\Users\...\Desktop\test\" + name2; // save the image in some path with filename.
                pictureBox1.ImageLocation = Path;
                bitmap.Save(Path,System.Drawing.Imaging.ImageFormat.Jpeg);
            }
        });
    }
    catch (COMException ex)
    {
        MessageBox.Show(ex.Message);
    }
