The Xerox WC 6015NNI (WIA) is a model of the Xerox WorkCentre 6015 series, which is a multifunction printer (MFP) designed for small office or home office use. The "WIA" part refers to the Windows Image Acquisition protocol, which is a standard for scanning devices in Windows. When a scanner (or multifunction device like the WC 6015) is used with a computer, the WIA driver enables the scanning functionality to work correctly within the Windows environment.
