About WIA Scanning

If your computer is running Windows Vista, you can use the WIA driver to scan originals on the machine from the computer via the network.

To use this machine as a WIA scanner, you must download the WIA driver from the supplier's Web site and install it on your computer.

The network TWAIN scanner function also allows you to scan originals from your computer; however, functions you can use differ between the TWAIN and WIA scanners.

The following table tells you the functions available or not available with the TWAIN and WIA scanners. For details about the TWAIN scanner, see "Scanning Originals with the Network TWAIN Scanner".
