7020

Parts change to the main control board requiring TYPE 2 Image firmware flash files.DESCRIPTION: SOLUTION ID:

117360

SOLUTION:

A manufacturing change has been made to the Image control portion of the main control board.

This change incorporates the 7035 type of Image control into all of the 7020, 7025 and 7030 main

control boards. This change is only a manufacturing change and does not affect machine

functionality. New 7020 main control boards (p/n 26NA-9305) and above have the TYPE 2 Image

control. To properly identify the board type that is installed in machines, perform the following:

1. Access the 25 mode (Power ON while holding down the 2 and 5 keys).

2. Select [8. Rom Versions].

3. In the Image control display a TYPE 1 or TYPE 2 designation will be displayed to the right of the

Image firmware version. Consequently, the Image Control firmware between the old type boards

(TYPE 1) and the new type boards (TYPE 2) are not interchangeable.

Notes:

1. The 7020 TYPE 2 Image firmware file (file name 7020-i30jp.exe) is available for download via

Konica NSSG Web support; select the Download EPROMs link and then select EPROMS for low

volume copiers. This TYPE 2 Image firmware is compatible with the current level 32 system

firmware (file name 7020-m32p.exe).

2. When flashing 7020 Image firmware via the ISWTRNS utility, be sure to select TYPE 1 or TYPE

2 accordingly. If the ISWTRNS utility program being used does not have the Image firmware TYPE

1/ TYPE 2 designation, download and install the latest ISWTRNS utility program. This utility (file

name ISWTRNS334E.EXE) is available for download via the Konica NSSG Web support; select

the Download EPROMs link and then select EPROMS for Accessories.

5. Power OFF/ON the subswitch to return to normal copy mode.

Note: The paper exit sensor assembly/2 (p/n 26NA-4920), which is the actuator for PS19 (Exit limit

detect), has been abolished on all 7020's starting with s/n 26NE23267. Due to this change, it is

necessary to set software switch 22-7 to a 1 to disable the function of PS19 (Exit limit detect). PS3

(Paper exit) is now used to count exited copies.
