DESCRIPTION OF ISW
ISW
ISW (In-System Writer) is a process of updating the control programs stored in flash ROM mounted on various control
boards in a Konica digital copier without isolating the boards from the copier. Running ISW enables you to upgrade control
programs without replacing the boards and maintain the boards during their replacement.
Tools available for running ISW include ISW Trns (PC software), which connects a personal computer (PC) to the digital
copier, and ISW Tool, which is a dedicated tool using EPROM.
These tools can be plugged into the ISW connector of the degital copier to directly update the control programs in flash ROM
assembled in the unit.
This chapter focuses on instructions on setting up the 7045 to run ISW. For how to run ISW Trns and ISW Tool, refer to Konica
ISW (In-System Writer) Servise Handbook.
Note: Procedures for using ISW Tools to update ROM data in Konica ISW (In-system Writer) Servise Handbook
are divided into three types by copier model. For this unit, see “Updating the Type B Model.”

SETUP
[1] Boards that Support ISW
1 OUTLINE
The following boards in the 7045 permit programs
that use ISW to be rewritten.
• CB (control board)
• ICB (image control board)
• DFCB (RADF control board)
• FNSCB (FNS control board)
[2] Operating Method
2 ISW
1. ISW connector
The ISW connector is next to the total counter in the
front door.
The connector (DC 5V jack) for the “ISW Tool” is
below the KRDS connector (25-pin).
The cap or seal that covers each connector must be
removed only when using it.

5. Types and quantity of re-write ROM
1 OUTLINE
When rewriting the copier flash ROM data using the
“ISW Tool” rewriting EPROM must be prepared.
The following table lists rewriting EPROM prepared
for this machine.
Caution: Quantity of the rewriting EPROM and
transfer file size are subject to change
without previous notice.

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.
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).
7. Data transfer error
The Print LED (amber) 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.
