SERVICE TOOL
1. Description of the ISW
ISW (In-system Writer) is an operation to rewrite the
control program stored in the flash ROM on a vari-
ety of control boards in the digital copier without
removing the boards from the main body of the
copier. ISW allows you to update the version of the
control program without replacing the board or to
install the latest program when replacing the board.
[ISWTrns (PC software)] is provided to execute
ISW, which rewrite the program by connecting a PC
to the digital copier. The software rewrites the con-
trol program stored in the flash ROM in the copier
main body directly.
This chapter only describes the set up procedure on
the main body for executing ISW. See the "ISW (In-
System Writer) Service Manual" for information on
operating the ISWTrns.
Note:
• When rewrite control program for new type,
be sure to use the ISWTrns Ver. 3.51 or the
above.
• When upgrading ISWTrns, be sure to uninstall
the current ISWTrns before installing the new
version. Installing it by overwriting may result
in the installation of the USB driver unavail-
able.
• It is required to install the USB driver for
ISWTrns to perform ISW via USB on this
machine. See the installation procedure for
the "2. USB ISW".
• Before performing ISW via USB, be sure to
turn on the USB radio button in [Setting (S)] -
[Set Communication (C)] in ISWTrns and
press the OK button.
• From "machine" list box of ISWTrns, be sure
to select "8050" for old type and "bizhub
C500" for new type.

The following shows the ISW data flow.
PC
OACB
Note:
• The control program on other boards cannot
be written until that for the overall control
board (OACB) is written.
1.1.3
ISW transfer type
The copier supports three ISW transfer modes as
follows.
A. Power ON mode
The power ON mode is used if no program is
installed on the overall control board (OACB) or it is
faulty.
If no program is installed on OACB, the OACB pro-
gram becomes possible to be written at power ON.
No display appears on the operation panel and the
timer LED flashes even if the operation board con-
trol program is installed because the OACB controls
the power for the operation board.
