Document scanning is integrated into the Job Workflow and happens automatically when you Run Job.

Scanning uses either the TWAIN or ISIS driver standard. For many scanners these drivers may need to be downloaded and installed separately from the WIA driver that installs automatically. They provide full access to the scanner functions versus the limited WIA interface.

ISIS drivers have better compatibility with high-speed scanner models, and the added advantage that scanner settings can be saved to the Job File to ensure standardization across multiple stations and scanning sessions.
