[1] General description

This machine is an option memory unit applicable to the machines

FO-4700 (100 or 200V series). It enhances the memory-aided functions

such as sequential simultaneous sending and through-memory sub-

stitute reception of facsimile.

[2] Installation procedure

(pay attention to static electricity)

To install the option memory unit, check the following in advance.

1) Make sure that the remaining memory capacity is 0%.

If the remaining memory capacity is not 0%, this implies that any data

remains in the image memory on the control PWB.

2) Check that a sufficient quantity of paper exists. If there is no paper or

paper is lacking, replenish the machine with paper, and print the data

received and stored in the memory.

3) Then, check whether there is any confidentially received information,

seeing the confidential reception data list ("FUNK" + "2" + "1" + "0"). If

any confidentially received information is found, input the ID No. of

specific reception box, and print the confidentially received informa-

tion.

4) After that, check whether there is timer sending information, seeing

the timer sending information list ("FUNK" + "2" + "0" + "2"). It is re-

quired to teach users that any timer sending information, if exists, is

cleared after the option memory unit is installed and, accordingly,

users have to set again the timer sending and do the timer sending.

Install the option memory unit in the following procedure.

1) Remove the ROM cover of facsimile.

2) Insert two spacers to control PWB, and then connect it to the connec-

tor CNOP of control PWB.

(Fig. 1)

3) Mount the control PWB to which the option memory has been con-

nected in the machine.

(Tighten the screws, and connect the connector without fail.)

4) Mount the ROM cover.

5) After installation turn on the power switch.

[3] Diagnostic mode

Successively input "FUNK" + "9" + " " + "8" + "#" + "7". Then,

appears.

After that, press the "START" key.

Then,

appears.

Select MEMORY CLEAR, using the one-touch key "11".

After completion of MEMORY CLEAR,

the following indication appears.

Select ROM/RAM test, using the one-touch key "03".

(This model is provided not only with flash memory for image but also

SRAM to enhance the function to store the number of transmissions

and receptions.)

When the "START" key is pressed again, the memory of machine

(control PWB) and memory of memory unit (excepting the flash mem-

ory) are checked.

An example of indication

After that, the indication shown below appears, and the result table

(Fig. 2) is printed.

After completion of ROM/RAM test the following indication appears.

Then, select the flash memory test, using the one-touch key "12".

In the diagnostic mode perform the image memory (standard, option)

write/read test, as well as complete erase test.

When the "START" key is pressed,

appears, and the indication changes from "–" to "■" whenever data is

written in the flash memory.

After completion of writing of data in all flash memories, the following

indication appears.

After that the long-tone buzzer (normal end) sounds, and at the same

time the following indication appears.

Then, the result table (Fig. 3) is printed.

In case of mismatch, the buzzer emits 9 short tones .

After that, the result table (Fig. 4) is output.

1) If any error occurred, check connection of connector CNOP (check

for bending and breakage of pin of connector), check that the option

memory unit has been mounted as specified, and then turn on again

the power supply, and check.

2) If the same error occurs persistently after the measures stated in item

1 above were taken, replace the option memory unit, and check.

3) If the same error occurs again after the measures stated in item 2)

were taken, check the control PWB.
