Operation procedure
Enter the 25 mode.
[25 mode screen]
Press the [11. ISW] key.
[ISW menu screen]
Select the ROM where the ROM data to be
rewritten.
[Program rewrite screen]
Pressing [START] key after [START] key is
displayed, cause the machine to be data waiting
condition.
Execute the operation according to the
procedures specified in the "Konica ISW
(In-System Writer) Service Handbook."

[1] Description of the ISW
ISW (In-System Writer) is an operation rewriting control
programs stored in the flash ROM included in the diverse
control board of a Konica digital copier with the board still
installed in the copier main body.
By implementing ISW you can update versions of control
programs without changing the board or carry out
maintenance of the control board when changing the
board.
Two ISW execution tools are prepared. One is the “ISW
Trns” (PC software) that implements rewriting by
connecting a personal computer (PC) and a digital copier.
And, the other is the specialized “ISW Tool” featuring
EPROM. These tools allow direct rewriting of the control
program 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”
and “ISW Tool,” refer to the “Konica ISW (In-System
Writer) Service Handbook.”
[2] Operating method
1. ISW connector
The ISW connector is provided on the right side face
of the copier. Of the two connectors situated in the
side face, the lower one is the ISW connector.
The connector (DC 5V jack) for the “ISW Tool” is
1
installed between the ISW connector (36-pin) and the
KRDS connector (25-pin). The cap or seal that
covers each connector must be removed before the
connector can be used.

Caution: The “Konica ISW (In-System Writer) Ser-
1
vice Handbook” describes three different
data rewriting approaches to be
executed by the ISW Tool. Applicable approach depends on the given model of the
copier. As for this copier, reference the
“Type B Re-write Operation.”

When rewriting the copier flash ROM data using the
“ISW Tool,” rewriting EPROM must be prepared.

4. Re-write precautions using the “ISW Tool”
System control ROM re-write
The re-write operation must be performed to divide the
EPROM of the system control ROM into two groups,
because of its number of “EPROM” is more tham 12. The
timing (first time data transfer end timing) for the second
time the re-write operations is performed is as follows.
transfer file size are subject to change
without previous notice.

5. Data transfer error
The FAX LED (amber) lamp lights if a transfer error
occurs. If an error occurs, refer to the section "Error
handling" in the separate “ISW Service Handbook” and
perform the appropriate countermeasures. After the
countermeasures are completed, perform the re-write
operation again from the beginning.
The data LED (green) of the operation part changes
from flashing to lighting.
The remaining EPROM is transferred to the “ISW
Tool” and the ROM data is transferred.
The LCD goes off during data transfer.

When data transfer is ended, the 25 mode menu
screen is displayed.
If an error occurs in the second ROM data transfer,
perform the operation again from the beginning (first
time).
