1. DESCRIPTION OF THE ISW
The ISW (In-System Writer) is an operation by
which the control program, that is stored in the flash
ROM incorporated into a variety of control boards in
the digital copier, is rewritten with the board inte-
grated into the main body of the copier. Executing
the ISW allows you to renew the version of the con-
trol program without changing the board or to install
the latest program while changing the board.
As a tool to execute the ISW, you can use the [ISW
Trns (PC software)] by which rewriting is made with
a personal computer (PC) connected to the digital
copier.
This tools allow direct rewriting of the control pro-
gram in the flash ROM included in the copier main
body by connecting the ISW connector of the copier
main body.
The method of carrying out the necessary setup
work on the main body for executing ISW is
described here. For the operation of the “ISW Trns,”
see the “ISW (In-System Writer) Service Manual.”
Note:
• When using the USB, be sure to turn on the USB
radio button in the [Setting (S)] - [Communication
setting (C)] of the ISWTrns and press the OK but-
ton.
• For the ISW method of this machine, only the
ISW Trns is available.
2. SETUP
A. Board used for the ISW
The following boards are available for rewriting
a program using the ISW in this machine.
• SCB (System control board)
• CB (Main body control board)
• FNSCB (FNS control board) : FS-112
• PWB-A FN (Main control board) : FS-114
• FAX control
• For the printer controller, see the Service Manual
of IP.
For boards other than the above, the ROM is
required to be changed.
B. Data flow
There are 2 types of data flows for the ISW as
shown below:
•PC→SCB→CB→FNSCB/PWB-A FN
•PC→SCB→FAX
Important:
• When the overall control program has not been
written into the SCB (System control board), it is
not possible to rewrite programs for other boards.
C. Checking before transfer
Before executing the ISW, be sure to check to
see if the transfer case and the transfer mode
to be used are correct.
(1) When the overall control program has not
been installed
When the overall control program has not been
installed, the LCD screen is not displayed and
data cannot be written in the 25 mode.
Transfer case: When the SCB (System control
board) is being replaced.
Transfer mode:When the power is on. (When
the data LED indicator lamp is
on → The ISW is waiting for
transfer. When the lamp is
flashing → The ISW is receiving
data.)
