TWAIN scanner plug-in | Photoshop CS6


Looking for information pertaining to the most current version of Photoshop? See TWAIN scanner plug-in.

TWAIN is an interface used to import from imaging devices, such as scanners. For more information, see the TWAIN Working Group's website. The Photoshop TWAIN plug-in connects with compatible devices that are installed on your computer.

Photoshop CS6 and TWAIN

TWAIN has been the main technology used for scanning in Photoshop for many versions. However, it is not always updated for new operating systems, and therefore may work less reliably than other scanning solutions, such as third-party utilities such as VueScan, the scanner software that comes with your scanner, or other scanning technologies. These third-party utilities are dedicated scanning solutions, and they are more appropriate for critical or high-volume scanning. If you use a third-party scanning application, save your scanned images as TIFF files, then open them into Photoshop.

TWAIN should work for basic scanning needs, but if you experience issues with TWAIN, try one of the other scanning technologies described below.

Note: To use any scanner technology, you need to install a scanner driver. This will probably be installed via your operating system, but you may need to contact your scanner manufacturer, especially for older scanners.

In Windows, the Photoshop TWAIN plug-in can be used if you run Photoshop CS6 or later in 32-bit mode. TWAIN is not supported in Photoshop when it’s run in 64-bit mode. If you need a scanning solution when you run Photoshop in 64-bit mode, use the WIA (Windows Image Acquisition) interface for your device, if it’s available. WIA is also available for use when running Photoshop in 32-bit mode. Contact your scanner manufacturer for more information.

In macOS, you can use the TWAIN plug-in to scan when running Photoshop CS6 (Photoshop CS6 and later only runs in 64-bit mode). Not many scanner manufacturers have released 64-bit versions of their scanner drivers, so you may not be able to use TWAIN. Contact your scanner manufacturer for more information.

If your scanner manufacturer does not support scanning in 64-bit mode, or you have issues scanning with TWAIN, you can scan into Photoshop using Apple’s ImageKit technology, which is built in to Photoshop, does not need a plug-in to be installed, and provides access to many scanners.

The TWAIN plug-in is available with the other optional plug-ins for Photoshop CS6 and later:

After you download the appropriate file, double-click the file to decompress it. If you are asked, extract all files.

Note: For Windows, the downloadable TWAIN plug-in is 32 bit only.

To install the TWAIN plug-in for Windows:

  1. Exit from Photoshop.
  2. Copy the Twain_32.8BA plug-in from the Optional Plug-ins Win32/Plug-ins folder to the appropriate folder below.
    1. Windows XP: \\Program Files\Adobe\Adobe Photoshop CS6\Plug-Ins\
    2. Windows Vista and Windows 7 (32 bit): C:\Program Files\Adobe\Adobe Photoshop [Version]\Plug-Ins\
    3. Windows Vista and Windows 7 (64 bit): C:\Program Files (x86)\Adobe\Adobe Photoshop [Version]\Plug-Ins\
  3. Reopen Photoshop.
  4. Download the latest scanner driver from your scanner manufacturer’s website and install the driver.
  5. Connect the scanner to the system.

To use TWAIN to scan images into Photoshop:

  1. Open Photoshop 32 bit by clicking the “Adobe Photoshop CS6 (32 bit)” shortcut.
  2. Select File > Import > [scanner name].


  1. Quit Photoshop.
  2. Copy the TWAIN.plugin file from the download folder to the Applications/Adobe Photoshop [Version]/Plug-ins folder.
  3. Reopen Photoshop.
  4. To use TWAIN in Photoshop, choose File > Import > [scanner name].

Troubleshoot TWAIN problems

When you use TWAIN to import from an imaging device, you may encounter problems like the following:

  • Photoshop or your scanner application freezes or quits unexpectedly.
  • You are unable to close the scanner window.
  • You encounter errors during import.
  • The preview of the imported image, or the imported image itself, appears incorrect onscreen.

Try the following solutions:


  • On 64-bit Windows, use the Windows Image Acquisition (WIA) interface to import from your device. For instructions, see Windows Help or contact your device manufacturer.
  • On 32-bit Windows, update the drivers for your device. For assistance with this process, see the website for the device manufacturer. If the problem persists with the most recent drivers, try one or both of the following:
    • Import from your device using WIA.
    • Using the software included with your imaging device, import and save images, and then open the saved images in Photoshop.


  1. Update the drivers for your device. For assistance, see the website for the device manufacturer.
  2. If the problem persists with the most recent drivers, import your image using another application, such as the Image Capture utility. See macOS Help or contact your device manufacturer for more information.
