							MX-2300/2700 N/G  ROM VERSION-UP  10 – 1
MX2700NService Manual [10] ROM VERSION-UP
1. General
A. Cases where version-up is required
ROM version-up is required in the following cases:
1) When there is a necessity to upgrade the performance.
2) When installing a new spare ROM to the machine for repair.
3) When installing a new spare PWB unit with ROM installed to it.
4) When there is a trouble in the programs in ROM and it must be
repaired.
B. Notes for version-up
(1) Relationship between each ROM and version-up
Before execution of ROM version-up, check combinations with
ROMís installed in the other PWBís including options.
Some combinations of versions may cause malfunctions of the
machine.
C. Update procedures and kinds of firmware
There are following methods of downloading of the firmware.
1) Firmware download using USB
2) Firmware download using media
3) Firmware download using FTP
4) Firmware download using Web page
• Firmware types
NOTE: If the MFPcnt PWB DIP SW No. 2 is not set to ON, an error
occurs.
2. Version-up procedure
A. Firmware download using USB
First you must install a USB print driver from the setup.exe
program in the MX-2300/2700 CD-ROM Disc 1
Create a folder on the root drive (usually C:\) of the PC. Name
the folder Pastel. Download the firmware (xxxx.sfu) and the
file2PRN program (File2PRN.exe) and place these files into the
pastel folder.
• Click on the firmware icon and drag it onto the  File2PRN icon
• The Imager will automatically enter simulation 49-99.
• If you open the print queue on the PC, you can see the firmware
loading for a few minutes.
• When the firmware finishes loading from the print queue, the
Imager display in simulation 49-99 shows the following:
S ***               E 
CAUTION DO NOT POWER OFF THE MFP! FIRMWARE
UPDATE IN PROGESS!
• At the completion of the upgrade, the Imager will reboot auto-
matically.
• Go to Simulation 22-05 and confirm the firmware has
upgraded successfully.Note: If the Imager locks up or loses power during the
upgrade, it could corrupt the firmware, preventing the imager
from booting up normally. 
If this occurs, you can rescue the firmware using the follow-
ing procedure:
•Rename the firmware file in the pastel folder to emup-
date.sfu
•Click on the emupdate.sfu icon and drag it onto the
File2PRN icon.
•The Imager will automatically enter simulation 49-99.
•If you open the print queue on the PC, you can see the firm-
ware loading for a few minutes.
•When the firmware finishes loading from the print queue,
the Imager display in simulation 49-99 shows the following:
S ***               E
CAUTION DO NOT POWER OFF THE MFP! FIRMWARE
UPDATE IN PROGESS!
•At the completion of the upgrade, the Imager will reboot
automatically.
•Go to Simulation 22-05 and confirm the firmware has
upgraded successfully.

B. Firmware download using USB device
(1) Firmware update from USB memory device
First you must install the firmware file (xxx.sfu) to the root of a
USB jump drive.
•If the firmware is in a folder, Simulation 49-01 cannot open
the folder.
•Secure Jumpdrive will not work.
•Must have a minimum of 32MB of storage capacity to load
the firmware onto it.
1) Insert the USB memory device into the main unit.
2) Enter the 49-01 screen. Press the button of the file to be
updated. The screen transfers to the update screen.
(In this screen, [FILE 1] is selected)
* The number of button changes depending on the number of
the file in the USB memory device inserted.
3) Current version number and the version number to be updated
will be shown for each firmware respectively.
Following key-codes will be changed;
NOW → CURRENT
NEXT → UPDATED TO4) Select the button of the firmware to be updated. The button will
be highlighted. (In this screen, [ICU(MAIN)] and [LANGUAGE]
are selected.) At the same time, [EXECUTE] button appears.
* Press the selected button again to release the selection.
* Press [ALL] button to select all items.
5) Press [EXECUTE] button. “ARE YOU SURE? [YES] [NO]”
becomes clear. If no button is selected, [EXECUTE] button is
gray out and cannot be pressed. Press [YES] to start the
update.
6) At the completion of the upgrade, the display will change to: 
COMPLETE: PLEASE TOUCH [OK] TO FINISH Press OK.
The Imager will reboot at this time.

7) Go to Simulation 22-05 and confirm the firmware has
upgraded successfully.
Note: If the Imager locks up or loses power during the
upgrade, it could corrupt the firmware, preventing the
imager from booting up normally.  If this occurs, you can
rescue the firmware using the following procedure:
•Rename the firmware file on the USB device to emup-
date.sfu
•Power off the imager (both switches) and insert the USB
device (Jumpdrive) into the USB port of the imager.
•Power on the imager
•The Imager will boot up into emergency update mode.
When finished, the display will read update completed
•Power off the imager, and remove the USB device
•Reboot the imager, and go simulation 22-05 to confirm
firmware has upgraded successfully.
C. Firmware download using FTP
FTP software is used to transfer the firmware data (extension “.sfu”) from the PC to the machine. The controller recognizes the firmware identi-
fier and the machine automatically switches to firmware write mode. After the firmware is updated, the machine automatically resets.
D. Firmware download using the Web page
A Web browser (service technician’s Web page) is used to update the firmware.
Update procedure
1) Start the Web browser on a PC and enter the specified URL. A special firmware upgrade page appears.
2) Click the “Update of Firmware” button in the Web page. Click the “Browse” button and select the firmware for the update.
