1. Power OFF both the sub switch (SW2), located on the operation panel and the main switch
(SW1) located on the left side of the copier.
2. Power on the main switch (SW1). Observe the SCANNER/PRINTER, FAX, and COPY
indicator lamps. Approximately 10 seconds after the main switch has been turned ON, all three
green indicator lamps should flash ON/OFF. This indicates that the OPRTS data transmission from
the main CB to the operation board has completed. If all three green indicators lamp remain OFF,
proceed to step 3.
3. Using a voltmeter (200V DC range) verify the 5V DC power supply from the main CB to the
operation board at CN81-1 and CN81-2 of the operation board.
4. Monitor the OPRTS signal on the operation board at CN80-4. When the main switch (SW1) is
powered on 4.8V DC should be measured. Approximately ten (10) seconds after power on, the
voltage should drop to 3.2V DC. If the voltage at CN80-4 remains 4.8V DC continuously, the
operation board has not recognized the serial data transmission sent from the main CB.
5. Replace the operation board (p/n 26NA-9031) as necessary.

How to identify if the main control board has type 1 or type 2 Image control firmware.DESCRIPTION: SOLUTION ID:
121718
SOLUTION:
To identify whether the machine has a type 1 or type 2 main control board, perform the following:
1. Power the copier OFF.
2. Access the 25 mode (Power ON while holding the 2 and 5 keys).
3. Select [8. Rom Versions].
4. In the Image control display a TYPE 1 or TYPE 2 designation will be displayed to the right of the
Image firmware version. TYPE 1 and TYPE 2 can also be identified by the part number on the main
control boards.
a. 7020 main control board (p/n 26NA-9304) or lower is a TYPE 1 board. Main control board
(p/n 26NA-9305) and above is a TYPE 2 board.
b. 7025 main control board (p/n 26SA-9302) or lower is a TYPE 1 board. Main control board (p/n
26SA-9303) or above is a TYPE 2 board.
c. 7030 main control board (26PA-9304) or lower is a TYPE 1 board. Main control board
(26PA-9305) or higher is a TYPE 2 board.
Notes:
1. The Image control firmware between the old type boards (TYPE 1) and the new type boards
(TYPE 2) are not interchangeable.
2. The TYPE 1 and TYPE 2 Image firmware files are available on for download via Konica NSSG
Web support; select the Download EPROMs link and then select EPROMS for the low volume
copiers.
The TYPE 1 and TYPE 2 Image firmware is compatible with the current level 32 system firmware.
When flashing Image control firmware via the ISWTRNS utility, be sure to select TYPE 1 or TYPE 2
accordingly.
3. 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
