[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 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 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 information.
4) After that, check whether there is timer sending information, seeing
the timer sending information list ("FUNK" + "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 ROM cov er of facsimile.
2) Insert two spacers to control PWB, and then connect it to the connector CNOP of control PWB.
(Fig. 1)
3) Mount the control PWB to which the option memory has been connected 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.

and receptions.)
When the "START" key is pressed again, the memory of machine
(control PWB) and memory of memory unit (excepting the flash memory) are checked.

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.
