Frequently asked questions for TSScan

TSScan will work with all modern document scanners and supports: page feeders, card scanners, slides/transparencies, and high-capacity scanners with full-duplex support.

Important: Fujitsu ScanSnap Series support added. Read more about this topic: here

TSScan creates virtual scanners on your remote desktop server which it then maps to your local scanners. This way you basically get a one to one scanner mapping on your terminal server.

No. You don't have any reason to install any drivers on your server but you also don't have to do anything else. The installation procedure takes care of everything and no more than five clicks are required to get TSScan up and running for all your users.

No. Just as TSPrint so is TSScan using the Microsoft Virtual Channels technology, so all traffic goes through the secured RDP connection. No need to forward or open any ports for TSScan to work.
Yes. You can use TSScan both on a internet connection and your local area network. It really makes no difference except the time required till the scanned document or image arrives on your remote desktop. But the difference is mostly minor.

Yes, TSScan does support NextGen. There is a little adjustment to be made. On a terminal server you have to delete the following file: C:\Windows\twain_32.dll .

Sometimes Windows caches this DLL and will restore it from its cache: C:\Windows\System32\ddlcache. Delete the twain_32.dll from this location also.

The most common error message assotiated with this issue is: "Unable to close the image device. StartScan: Cannot close Data Source. DG Dat MSG out of expected sequence. Value1:0, Value2:0."

You can also solve this issue by downloading and running this application on your terminal server: NextGenFix

To resolve this issue please delete the following registry key from your user profile:
HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Twain
To resolve this issue please delete the following registry key:
HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Twain
Most of the time when users experience this issue it is happening because the application from which you are scanning is configured to scan only a single page but TSScan in return is configured to auto-detect the number of page. To resolve this please make sure that your application is configured for multipage or feeder scanning. This will then load all images which TSScan scanned to the application.
To resolve this issue please make sure that you have at least TSScan Server version 2.8.8.8 installed on your terminal or citrix server.
When the TSScanConsole.exe throws a error message from your local workstation it is mostly happening because of a corrupt TWAIN driver.
TWAIN drivers are located in C:\Windows\twain_32\.

Now remove folder per folder in that directory and check if the error message still shows up. When it stops appearing you should know which driver was causing the issue. Now try to find a newer release of the driver or re-install it.
No. The product installation doesn't require any reboots before you can use it.


Log in to the workstation where the scanner is connected / installed to.

If Citrix receiver was installed by a user with administrative rights, do the following:
Open the registry editor (regedit) and locate the following:
HKEY_LOCAL_MACHINE - SOFTWARE - Citrix - ICA Client - Engine - Configuration - Advanced - Modules - ICA 3.0
Right click 'VirtualDriver' and delete 'TwainRdr,' from it. Press 'OK' and close the registry editor.

If Citrix receiver was installed by a user without administrative rights, do the following:
Open the registry editor (regedit) and locate the following:
HKEY_CURRENT_USER - SOFTWARE - Citrix - ICA Client - Engine - Configuration - Advanced - Modules - ICA 3.0
Right click 'VirtualDriver' and delete 'TwainRdr,' from it. Press 'OK' and close the registry editor.

When using vWorkspace with TSScan, users experience communication error

The resolution is to install fixes from the following links depending on your client system. One is for 32bit machines, the other is for 64bit machines.

vWorkspace communication error fix x32 client


vWorkspace communication error fix x64 client

Take a look at this short video tutorial on how to install the TSScan client for MacOS.


You can find the list of supported scanners on Apple official page.

We added support for Citrix and all RDP clients on MAC
You can activate the communication by opening TSScan on the server Desktop. Once opened under tools as described in the picture below, you can activate the MAC communication.



After you switch to it, the window will close and you will be able to see the TSSCan MAC window as below.



When you see the TSScan window as shown in the picture above, simply start scanning and the communication with your MAC will be established.

The device is not open is a common issue where the local scanner is unreachable by TSScan.
The example below (TSScan Server on 2012R2).



As a first suggestion, you could try to check the scanner UI box as it would give you a driver error provided by the scanner manufacturer directly to see if there is another issue with the communication. You can also try and open the following tool on the client-side to see if the driver is working still on your PC as it should:
IrfanView
Try Locating your scanner under File-Select Scan/Twain Source and now try to scan by going into File>Acquire/Batch scanning. Your scanner needs to be visible and working locally, so it's usable by TSScan in the session.

Also, if none of the steps above helped you can try turning your scanner OFF and ON again to see if the connection will be established again with your local PC.

The image below shows the options you receive with TSScan server after the installation.
All settings can be applied on per user basis or if opened as Administrator to all users connecting to this server.



To revert your TSScan 3 to the previous TSScan protocol and usage of the system, you can just un-check the Dynamic Redirection feature shown above. Such a change will result in the scanning behaving as if you still used TSScan 2. All calls issued after the change was made go through the original twain_32_system.dll.

NOTE: This would be recommended only in case your application is having some problems with the TSSCan 3 version you have on the server.

To resolve this issue caused by the latest Microsoft Remote Desktop application version, please follow the steps below:

1. Make sure you're running the latest version of the TSScan Client as well as the TSScan Server.
You can download the latest client version 1.7.0.5 here.
And the server version 3.0.4.22 here.

After you have installed the latest version before you connect to the remote session, please do the following:

2. Open the Microsoft Remote Desktop application and click on the small edit button as marked on the image below.

MAC01


3. Redirect the TSScanDrive folder into the remote session by clicking on a "plus" sign in the bottom left corner, as marked on the image below. Make sure to select the folder called TSScanDrive located in your Documents folder. Click on "Save."

MAC02


That should do the trick. Now connect to the remote session and start scanning!

Yes, ScanSnap scanners are supported with the TSScan but only with TSScan version 3.0.5.13 or higher.
To set up the TSScan with your ScanSnap scanner, please follow the steps below:

1. Make sure that the ScanSnap Manager is installed on your local PC.
This is the main requirement for the ScanSnap to work with the TSScan. If the ScanSnap Manager isn't installed, the ScanSnap device won't be visible as a source in the TSScan application.

2. If you're using the TSScan as a scanner from your application, select the TSScan as a source


3. The ScanSnap should show as a source now in the TSScan application


And the settings for your new ScanSnap scanner should be available now:


Please note that the TSScan Scan Engine 3.0 doesn't support ScanSnap as a source.
