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.

originals to electronic data.
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.
