Relay User Box is a box used to relay data when you use this machine as a relay machine to the facsimile.
When you send a fax to the relay machine using the relay distribution function, the relay machine sends the received fax to all recipients pre-registered in the Relay User Box.
Using the Relay User Box, you can reduce the total communication cost via the relay machine, for example, when you want to broadcast to distant places.
Select [Box] - [System User Box List] - [New Registration] - [Relay User Box] in user mode of Web Connection (or in [Utility] - [Utility] of this machine), and configure the settings. For details, refer to [Relay User Box].
