Scanning into CS Professional Suite applications requires a TWAIN-compliant scanner. If your imaging device is not being recognized or is experiencing other issues scanning into one of these applications, you can perform a test outside a CS Professional Suite application to see if your scanner is indeed TWAIN compatible and that its driver is functioning properly. As not every scan job you perform locally on your machine will utilize the TWAIN driver, you will need to use a specific 3rd-party utility for this process, such as Twacker.

Twacker (also known as Twack) is a widely trusted utility for testing TWAIN-compliance and performance. It can be downloaded (as a 32-bit or 64-bit .MSI file depending on your Windows OS version) in the Tools section on TWAIN.org External link . (What's this?)

We provide access to these resources for your convenience, but we are not responsible for their accuracy. If you need additional assistance, please consult your qualified technician and/or the vendor who developed the resource.

Once it has been downloaded and installed, follow the steps below to test your scanner:

  1. Launch Twacker. This will open a small window that looks similar to Notepad.
  2. Choose File > Select Source and select your device from the list.

    Note: If your device is not even listed and you've confirmed it is indeed on and connected to your machine, check to see if the appropriate driver is installed. If assistance is needed with this, contact the device's manufacturer and/or your qualified IT professional. Additionally, Twacker may need to be ran as "Admin" if you don't have the proper permissions to access the data source.

  3. Once your scanner is selected, choose File > Acquire. This will pull up your device's scanner dialog box where you can select your settings and attempt to scan a document.
  4. If the scan completes successfully without errors, then your device is functioning properly and should be TWAIN-compliant (though it does not guarantee you will be able to scan into all other applications).

If your scanner does not work with Twacker, it most likely will not work with any other program that requires a TWAIN driver, including CS Professional Suite applications. Consider installing the most current TWAIN driver for your scanner model from the manufacturer's website. If you need assistance with that process or other related steps to resolve any issues with your TWAIN driver(s), contact your device's manufacturer and/or your qualified IT professional.

Internal notes


If you need to install Twacker yourself, or need to send it to the firm rather than having them download from the TWAIN.org website. You can download the -Twack_32.zip file and unzip it. Copy and paste the Twack_32.exe file to your Desktop before running it or attaching it to a message.

Note: If emailing this file to a user, remember to rename it first because email will most likely block .exe attachments.
