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