MX-3114N 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.
1)
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 fol-
lowing points:
When the power is shut down or an abnormality 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, however, an abnormality occurs in the boot program, the SD
card 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 abnormal-
ity in the main program.
2)
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.)
3)
ROM making function
(This function is not used in the market, and not described in
this manual.)
b. Purpose
This function is used in the following cases:
1)
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, however, an abnormality occurs in the boot program, the SD
card must be replaced with a new one having the normal boot
program.
If an error occurs in the boot program, this method cannot be
used. In such a case, the SD card 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.
