What device allows for the rapid scanning of multiple papers by feeding them quickly into a scanner?

The Automatic Document Feeder (ADF) is designed specifically for the rapid scanning of multiple pages. It allows documents to be loaded in bulk, enabling the scanner to process them in a continuous manner without the need for manual handling of each individual sheet. This feature is especially useful in environments where high-volume scanning is required, such as offices or document management scenarios.

In contrast, a flatbed scanner typically requires documents to be placed on a glass surface one at a time, making it less efficient for scanning multiple pages quickly. A sheet-fed scanner also scans documents similarly, but often represents a standalone unit that might not have the same integrated capabilities for batch scanning as an ADF-equipped device. A document scanner is a broader term that can encompass various types of scanning devices, but it does not specifically denote the capability of rapid multi-page scanning, which directly pertains to an ADF.
