Level 32/28 firmware upgrade does not change the DO NOT COPY stamp/watermark to
COPY.
DESCRIPTION: SOLUTION ID:
116270
SOLUTION:
CAUSE: System control firmware bug.
SOLUTION: Update firmware to the following levels:
1. Flash the 7020 System control firmware to level 32 (file name 7020-M32CGDOP.EXE) or
higher.
2. Flash the 7020 Image control firmware to level 31 (file name 7020-I31IP.EXE Image Control
Type 1 board or file name 7020-I31JP.EXE Image Control Type 2 board).
Notes:
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.
4. The 7020 TYPE 1 Image firmware file (file name 7020-I31IP.EXE) and the 7020 TYPE 2 Image
firmware file (file name 7020-I31JP.EXE) is available for download via Konica NSSG Web support;
select the Download EPROMs link and then select EPROMS for low volume copiers.
5. This TYPE 1 and TYPE 2 Image firmware is compatible with the current level 32 system
firmware (file name 7020-M32CGDOP.EXE). When flashing 7020 Image firmware via the
ISWTRNS utility, be sure to select TYPE 1 or TYPE 2 accordingly.
6. 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.
