2.4. Scanner

2.4.1. Purpose

The purpose of the scanner is to provide mechanical transport of hardcopy originals and to convert hardcopy
originals to electronic data.

2.4.2. Hardware

The scanner converts the image from hardcopy to electronic data. An optional document handler moves originals
into a position to be scanned. The scanner provides enough image processing for signal conditioning and
formatting. The scanner does not store scanned images. All other image processing functions are in the copy
controller.
The DADF/Scanner contains a CPU, BIOS, RAM, and Non-Volatile Memory
