Fax Security*

Canon imageRUNNER devices that support Super G3 fax capabilities with the optional Super G3 Fax

Board installed can be connected to the Public Switched Telephone Network for sending and receiving

of fax data. In order to maintain the security of customer’s networks in relation to this potential

interface, Canon has designed its Super G3 Fax Boards in the following manner:

• There is no functional module such as a Remote Access Service that enables communication

between a phone line and a network connection within the device.

• The Super G3 Fax Boards cannot receive data files, but are only capable of receiving and

decoding facsimile transmissions. As a result, virus-laden files sent to an imagePlatform

device via its phone line connection cannot be processed.

• The modem on the Super G3 Fax Boards does not have Data Modem capability, but only Fax

Modem capability. As a result, TCP/IP communication through the phone line is impossible.

Even if the device receives a data file pretending to be a FAX image data but contains a virus,

the received data must be decoded first. While trying to decode the virus the phone line will

be disconnected with a decode error and the received data will be discarded.

• Although a received fax document can be accessed from the network through the

Confidential Fax Mail Box function inherent in the device, or automatically forwarded to a

network it is not possible to breach the network in either instance, as these capabilities are

afforded following completion of facsimile communication. Since the data stored in the

Confidential Fax Mail Box is in fax format, there is no threat of virus infection.

• The PC Fax function can fax documents from the PC via Network, using a Fax driver that runs

on the PC. However, data transfer from the PC via Network to the device and data transfer

(FAX transmission) from the phone line via the G3 FAX board is structurally separated.

• Fax Polling is the only function that enables users to handle documents stored in a polling

box. Any action associated with these documents stored in a polling box is performed using

G3 Fax protocols, which provide no means of accessing a local network.
