ISW
[1] ISW-compatible boards
The 7075 allows ROM data residing on the
following boards to be updated via ISW Tool:
- Image control board
- Printer control board
- Operation board
- RADF control board
- Video I/F board
The ROMs of other boards than the above need
to be replaced.
[2] Data flow
Important Note:
The availability of the Graphics control board is
prerequisite to updating ROM data on other boards.
[3] Ready up the copier to start an ISW
transfer
1. Transfer modes
The copier supports three transfer modes as
described below.
- Power-on mode
If the copier does not have the image control
program installed, its writing to the copier is
enabled when the main switch is turned on. Be-
cause the image control board controls the power
supply to the operation board, nothing will ap-
pear on the operation LCD and timer LED will
blink even though the operation control program
has been installed on the copier.
- HELP + CHECK mode
Turning ON the copier with HELP and CHECK
puts it into the HELP + CHECK mode. If the copier
has the image control program installed, but not
the operation control program, the 25 mode would
not launch. This mode is specifically maintained
to enable ISW in this situation.
SETUP
PC/ISW Tool Image control Operation board
Printer control board
RADF control board
Video I/F board
2. 25 mode
The 25 mode works only where the copier has
both the image control and operation control pro-
grams installed.
(Some part of HELP+CHECK mode is used to
update the operation control program in 25
mode.)
