2.3Fax Module

2.3.1.Purpose

The embedded FAX service uses the installed embedded fax card to send and receive images over the telephone interface.

2.3.2. Hardware

The fax card connects directly to the Main Controller processor card. The fax card does not have its own processor and local memory but uses the Main processor and reserved Flash memory. The card contains a fax-only modem that supports the T.30 protocol. If anything other than the T.30 protocol is detected, the modem will disconnect. Internal logical interfaces maintain separation between Fax and network.

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 main controller.
