MX-7040N  FIRMWARE UPDATE  8 – 3
B. Firmware update 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.
C. Firmware update using the Web page
An Web browser (service technician’s Web page) is used to update
the firmware.
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" key in the Web page. Click the
[Browse] key and select the firmware for the update.
3)
After selecting the file, click the [Submit] key to send the firm-
ware to the machine. Update processing begins. While pro-
cessing takes place, "Firmware Update, now processing..."
appears.
4)
When the firmware update is finished, "Firmware Update com-
pleted. Please reboot the MFP." appears. Pressing the
[Reboot] key, the machine will restart to complete the update.
The browser will shift to the following screen.
"Close the browser and open again to display latest informa-
tion." will be displayed.
5)
Check the firmware version of machine again.

MX-7040N  FIRMWARE UPDATE  8 – 4
D. Firmware update using the CN update function 
(There are three methods.)
(1)
Outline
The update method using the DIP SW of the MFP PWB is called
the CN update.
a. Function
There are the following three functions in the CN update mode.
• Firmware update function
This function is used to update the firmware by transferring data
from the PC which is connected to the MFP PWB, the SCU
PWB, the PCU PWB, the FAX PWB, and various options by
means of a USB memory or USB cable.
This is basically the same as SIM49-01, but differs in the follow-
ing points:
When the power is shut down or an abnormality occurs in a sec-
tion other than the boot program for some reasons during firm-
ware update operation of other method than the CN update, this
method can be used to update the firmware.
If, however, an abnormality occurs in the boot program, the SD
card and CompactFlash must be replaced with a new one having
the normal boot program.
If the boot animation is not displayed, there is an abnormality in
the boot program.
If the boot animation is displayed but "Copying is enabled" is not
displayed on the copier basic menu, there is an abnormality in
the main program.
• Firmware version check function
(The method to check the firmware version by using SIM22-5 is
easier than this method. Therefore, it is not described in this
manual.)
b. Purpose
This function is used in the following cases:
• When an error occurs during firmware update operation other
than the CN update.
• When the power is shut down or an error occurs in a section
other than the boot program for some reasons during firmware
update operation of other method than the CN update, this
method can be used to update the firmware.
If an error occurs in the boot program, this method cannot be used.
In such a case, the SD card and CompactFlash must be replaced
with a new one having the normal boot program.
c. DIP-SW used in the CN update mode
To enter the CN update mode, turn ON the UPDATE DIP-SW on
the MFP PWB and boot the machine. 
When terminating the CN update mode, reset UPDATE DIP-SW to
OFF (normal mode).
d. Keys used in the CN update mode
The following five keys are used for operations in the CN update
mode. Be careful that the functions of the keys differ those in the
normal mode.
(2)
Operating procedures
a. Firmware update function
This function is used to revise the firmware by using the USB mem-
ory for the MFP PWB, the SCU PWB, the PCU PWB, the FAX
PWB, and each option.
It is basically same as SIM 49-01, but differs in the following points.
• The update target ROM is automatically selected.
• When the power is shut down or an abnormality occurs in a sec-
tion other than the boot program for some reasons during firm-
ware update operation of other method than the CN update.
If, however, an abnormality occurs in the boot program, this method
cannot be used. On that case, the SD card and CompactFlash
must be replaced with a new one having the normal boot program.
When the boot animation is displayed but "Copying is enabled" is
not displayed on the copier basic menu, there is an abnormality in
the main program (SD card or CompactFlash).
a-1. Necessary items
1)
Insert the SD card and CompactFlash to the MFP PWB of the
machine. 
2)
USB memory with the firmware file (SFU) saved in it.
NOTE: Save the firmware file in the main directory or in a one-level
lower directory.
