[1] General description
This machine is an Option Memory Unit applicable to the FO-6700. It enhances the memory-aided functions such as sequential simultane­ous sending and through-memory substitute 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 Main 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 ("FUNC" + "2" + "1" + "0"). If any confidentially received information is found, input the ID No. of specific reception box, and print the confidentially received informa­tion.
4) After that, check whether there is timer sending information, seeing the timer sending information list ("FUNC" + "2" + "0" + "2"). It is required 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 Rear Cabinet of facsimile.
2) Loose two screws on the Standard Memory PWB and remove two spacers. Then, remove the Standard Memory PWB from two locking spacers and the connector.
3) Connect the Option Memory PWB to the connector CNOP of Main Control PWB and insert two locking spacers into the holes on the board. Then, tighten two screws with each spacers. (Fig. 1)
4) Mount the Rear Cabinet.
5) After installation turn on power switch with pressing "ST ART" + "STOP" key.
[3] Diagnostic mode
Successively input "FUNC" + "9" + " " + "8" + "#" + "7". Then, appears.
ROM:FAB0
After that, press the "START" key. Then, appears.

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.

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 Main Control PWB.
