FO-8MK
[1] General description
This machine is an Option Memory Unit applicable to the FO-4400 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 ("MENU" + "2" + "0" + "9").
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 ("MENU" + "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 CNOP1 of 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" + "ST OP"
key.
