If i try to use this scanner, with the USB-Interface
everything is all right.

If I try the same and use the NetWork Interface
and I acquire some data from the scanner I get no response.
I only cann stop the application by using the task manager.
The problem occurs with Windows XP, Vista and Windows 7.

If I use the Office tool Microsoft Document Scanning
the scanner works without any failure.

Now I am capable to scan with Nwtwork Interface.
I Have got one existing Problem:
If I use the autofeeder the Acquire-Function works properly
and adds all the pages to the IEMVIEWEN-Window and the
the scanner-Window ist closed.
Just at the end I get as division by zero error.
All Parameter I tried to set had the same result.

I paste a few Code lines, perhaps anybody has got the reason
for this effect.
thank you for your help!


IEMVIEW.MIO.TwainParams.PixelType.CurrentValue:= 0;
if (IEMVIew.MIO.TwainParams.PaperDetectable= True)
then begin
IEMVIEW.MIO.TwainParams.FeederEnabled:= True;
IEMVIEW.MIO.TwainParams.AutoFeed:= true;
IEMVIEW.MIO.TwainParams.DuplexEnabled:= False;
end;
IEMVIEW.MIO.TwainParams.CompatibilityMode:= False;
IEMView.MIO.TwainParams.VisibleDialog:= False;
IEMVIew.MIO.TwainParams.BufferedTransfer:= True;
IEMView.MIO.TwainParams.FileTransfer:= True;
IEMVIEW.MIO.TwainParams.StandardSize.CurrentValue:= IETW_A4;
IEMView.MIO.TwainParams.UndefinedImageSize:= True;
IEMVIEW.MIO.TwainParams.UseMemoryHandle:= False;
IEMView.MIO.TwainParams.ProgressIndicators:= False;
IEMVIEW.MIO.TwainParams.Update;
if (IEMVIEW.MIO.TwainParams.CapabilitiesValid = False)
then IEMVIEW.MIO.TwainParams.GetFromScanner;
IEMVIEW.MIO.TwainParams.Update;
try
ok:= IEMVIEW.MIO.Acquire;
IEMVIEW.MIO.TwainParams.FreeResources;
except
end;


Anybody any Idea, what could be the reason.

Best regards .

Hi Chouk,
the scanner driver must be made for this. Installing the driver (maybe a specific driver for network device) it is seen by ImageEn as a local device.

Hi Chouk,

you need to install a network Twain-Driver for the scanner
or if it's an usb-device you have to attach the
scanner to a USB-Multifunctions-Server.
With the new Beta this works fine!

Thanks to Fabrizio who helped me a lot!
