Setting SUB Codes for Transmission
This section explains how to use a SUB Code so that you can send a document as a confidential document or send a document via a transfer station.
A SUB Code is an ID consisting of numbers, #, *, and spaces.
Confidential transmission
Documents sent by confidential transmission are stored in the other party's memory and are not printed automatically. The other party enters the SUB Code to print the received document. Privacy can be mutually protected when transmitting a confidential document intended for a specific receiver, since only the person who knows the SUB Code can print the document.
To perform a confidential transmission, you must specify a machine that has the Personal Box function as a destination.
Transmission via a transfer station
If you send a document via a transfer station, you can reduce costs when you send the same document to multiple remote destinations. Also, you can save time since many documents can be sent in a single operation.
To send via a transfer station, you must specify a machine that has the Transfer Box function as a destination.

Before sending a fax, first register a SUB code for the destination in the address book.
