[Relay User Box]
When you use this machine as a relay machine to the facsimile, the Relay User Box is used for data relay.
If you use the Relay Distribution and when you send a fax to the relay machine, it distributes the fax to all recipients being registered in the Relay User Box.
If you are using broadcasting to distant places, you can reduce the total communication cost by using the relay machine.
To use this machine as a relay machine to facsimile, you need to create a Relay User Box and set the recipients.
To use this function, the optional Fax Kit is required. bizhub C3851FS/C3851 provides the Fax Kit as standard.
This machine can request another relay machine to relay fax documents. For details on how to request a fax relay, refer to [Sending a Fax after Specifying a Relay Station (F-Code TX)] .
