On a Windows Vista-based or Windows Server 2008-based computer, you install a Web Services on Devices (WSD) scanner device that does not support event notification. On this WSD scanner, a Windows Image Acquisition (WIA) image transfer may fail.

Windows Image Acquisition: A driver model and application programming interface (API) for modern Microsoft Windows operating systems that enables graphics software to communicate with imaging hardware such as scanners, digital cameras and Digital Video-equipment.

You use the Windows Image Acquisition (WIA) scanner on a Windows Vista-based computer to perform a scan in an application, such as Adobe Photoshop. If you click Cancel during the scan operation, the application does not function correctly. For example, you may experience one or more of the following symptoms:

• You receive an error message.
• The application stops responding.
• The application crashes.

Customized property pages in the Advanced Settings dialog box are not displayed in the Windows Image Acquisition (WIA) scanner Properties dialog box on a Windows Vista-based computer. For example, the Duplex Scan setting is not available. The Duplex Scan setting can only be changed in the Advanced Settings dialog box. Additionally, you cannot change other customized advanced settings.

Windows Image Acquisition (WIA) imaging software may stop responding (hang) in Windows Vista. For example, when you try to use an image scanner, the scanner software may stop responding.
