This chapter explains F-code transmission, which gives you a convenient means
of performing advanced operations such as relay broadcast transmission and
confidential transmission. Normally these functions require that the other fax
machine be a similar Sharp machine; however, F-code transmission enables
these functions to be performed with any other machine that supports F-code
transmission. Please read those sections which are of interest to you.

This machine supports the "F-code" standard as established by the ITU-T*.
Operations such as relay broadcast transmission and confidential transmission previously could only be performed with
another Sharp fax machine; however, F-Code communication makes it possible to perform these operations with fax
machines of other manufacturers that support F-Code communication.
Before using the functions explained in this chapter, make sure that the other fax machine supports F-Code communication
and has the same functions as your machine. (the other machine may use a different name for the function).

* The ITU-T is a United Nations organization that establishes communications standards. It is a department of the International

Telecommunication Union (ITU), which coordinates global telecommunications networks and services.

"Memory boxes" can be created in the memory of fax machines that support F-Code communication. These boxes are
used to store faxes received from other machines and documents to be transmitted when a polling request is received. 
Fax machines that support F-code transmission enable the creation of a "memory box" in the unit's memory. Up to
50 memory boxes can be created for a variety of purposes, and a name can be assigned to each box. A "sub-
address" that indicates the box's location in memory must be programmed, and if desired, a passcode can also be
programmed to control access to the box. (A sub-address must be programmed, however, a passcode can be
omitted.)

*The Public Box is used for normal serial polling (see "USING POLLING MEMORY" on page 3-7).

When communication occurs involving a memory box, the communication will only take place if the sub-address and
passcode that the other machine sends match the sub-address and passcode programmed in your machine for that
box. Therefore, to allow communication, you must inform the other party of the sub-address and passcode of the
memory box. Likewise, to send a document to a memory box in another machine or use polling to retrieve a
document from that memory box, you must know the sub-address and passcode of that memory box. (Box names
are used only to manage boxes in the machine; you do not need to inform the other party of a box name the other
party only needs to know the sub-address and passcode.)
This machine uses the term "sub-address" for the location of the memory box and the term "passcode" for the
authorization number of the memory box; however, the products of other manufacturers may use different terms.
When asking the other party for a sub-address and passcode, you may find it useful to refer to the 3-character
alphabetical terminology used by the ITU-T.

When transmitting to a memory box in another fax machine, the sub-address and passcode must be entered after
the other machine's fax number. Enter the other machine's fax number as explained for a normal transmission (page
2-2) or for a polling operation (see "USING THE POLLING FUNCTION" on page 3-6), and then enter the sub-address
and passcode as follows:

If the condition settings
screen appears, touch
the [ADDRESS
DIRECTORY] key to
display the address
directory screen (refer to
page 1-4).

If the sub-address and passcode have been
programmed into the one-touch key, the following
steps are not needed.

When the [SUB
ADDRESS] key is
touched, a slash "/"
appears at the end of the
fax number. If you make
a mistake, press the [C]
key to clear the mistake.

If you make a mistake,
press the [C] key and re-
enter the correct digit(s).

A slash "/" appears at the end of the sub-address.

If a passcode has not been established for the
other box, this step is not necessary.

Operations that use F-Code memory boxes include F-Code polling memory (following page), F-Code confidential
transmission (page 4-6), and F-Code relay broadcast transmission (page 4-8). To perform these operations, a
memory box for each type of transmission must be created.
Memory boxes are created in the custom settings. Up to 50 boxes can be created.

The information programmed in each memory box varies slightly depending on the type of
operation. Refer to pages 6-10 to 6-14 for the procedures for creating, editing, and deleting
memory boxes.

After you have programmed a memory box, inform the other party of the box's sub-address and passcode.

You can program a sub-address and passcode into a one-touch key along with the fax number (refer to page 6-
3 to 6-4).

●

Manual transmission (on-hook dialing) using a sub-address and passcode is not possible.

NOTE
If you attempt to create a box when 50 boxes have already been created, a message will appear and you will not
be able to create the box. First delete an unused box (See "EDITING AND DELETING A MEMORY BOX" on page
6-14.), and then create the new box.

F-code polling memory allows one fax machine to call another fax machine and activate reception of a document
that has been scanned into the other machine's F-code polling memory box. Calling another machine and
activating reception is called F-code polling, and scanning a document into a memory box for another machine to
retrieve by polling is called F-code polling memory. This function is approximately the same as normal polling
explained on page 3-5; however, it uses an F-code polling memory box and is always protected by means of the
sub-address and passcode.

■ How F-code polling memory works

F-code polling is when your machine calls another machine and retrieves a document that was scanned into the
polling memory box of that machine (the reverse of the above diagram).

In order for another machine to retrieve a document from your machine, you must first scan the document into the
F-code polling memory box.
You can check scanned document data by printing it out (refer to "Checking and clearing document data in a
memory box" on the following page).

■

■

■

■ Scanning a document into an F-code polling memory box

The procedure for scanning a document into an F-Code polling memory box (page 6-10) is similar to the procedure
for scanning a document into the polling memory public box. Instead of touching the [PUBLIC BOX] key in step 5
of "Scanning a document into memory (Public Box) for polling memory" on page 3-7, touch the key of the memory
box into which you wish to scan the document. If document data has already been stored in that box, a new
document data will be added on to the existing data. If you no longer need the existing data, delete it as explained
in "Checking and clearing document data in a memory box" on the following page.

When you touch the memory box into which you wish to scan the document, the
key is highlighted and selected as the scanning destination.

●

To perform polling or polling memory without using an F-code, refer to page 3-5.

●

To create an F-code memory box for polling memory, refer to page 6-10 and "Polling times" on page 6-11.

●

Unlike normal polling, the other machine's fax number is not programmed as a passcode for F-code polling
memory. The sub-address and passcode of the polling memory box are always used for polling security.

●

The receiving machine bears the expense (phone charges) of the transmission.

NOTE
When using F-code polling memory, do not set the reception mode to manual reception.

NOTE
When creating the memory box, you can select whether to have the scanned
document data automatically cleared after polling, or left it in the box to allow
repeated polling.
