Sharp MX-FX13 User Manual

F-Code confidential transmission provides a secure means of faxing confidential documents. The sub-address and 
passcode programmed in the box restrict the recipients of the fax, and once received in the box, the fax can only be 
printed by someone who knows the print passcode.
This function is convenient when sending important documents that you only want a specific person to see, or when 
multiple departments share a single fax machine.

As the above diagram shows, receiving faxes to the machine's F-code confidential memory box is called F-code 
confidential reception, and sending faxes to another machine's F-code confidential memory box is called F-code 
confidential transmission.

To perform F-code confidential transmission, you must enter the sub-address (SUB) and passcode (SID) after the 
fax number of the receiving machine. (Omit the passcode if the other machine does not use a passcode.
To receive a fax sent by F-code confidential transmission (this is called F-code confidential reception), you must 
inform the sending party of the sub-address (SUB) and passcode (SID) of your confidential box. (Omit the passcode 
if a passcode is not programmed in the box.)

• This machine does not support Sharp's previous confidential transmission function, which uses the 

programmed sender's fax number and ID code.

• See pages 78 through 82 for the procedures for creating, editing, and deleting F-code confidential memory 

boxes.

• Take care not to forget the print passcode that is programmed in the F-code confidential box. If you forget the 

passcode, consult your Sharp dealer.

An F-code confidential transmission can be used in combination with the broadcast transmission function (page 
31) or the timer transmission function (page 33), and can be stored as a program (page 76).
