Points to note
when using
an HDD with
system software
already installed
Use of an HDD in which the system software of another machine (a machine of
a different serial number) is installed for a troubleshooting is possible if it is an
HDD of a model of iR-ADV C5255 series and later. However, be sure to format it
after installing it. Operation is not guaranteed if it is continued to be used as is.At
installation, HDD must be formatted. Therefore, it is not recommended to use an
HDD which has been used with another machine.If you use an HDD which has
been used with another machine, be sure to get agreement from user in advance
that user data will be deleted.
In addition, an HDD used in iR-ADV C5255 series and later cannot be accessed
from a PC due to enhanced security.

Refer to “Removing the Main Controller PCB 2”.
Before
Replacement
Data in SRAM on the Main Controller PCB 2 can be backed up to a USB memory
device or an HDD from download mode.
* However, if the HDD Encryption Board is installed, backup to an HDD is not
possible. It is therefore recommended to perform backup to an USB memory
device.
Preparation:
USB memory device where the system software for this machine has been
registered using the SST
Or, USB memory device formatted as FAT32 which has been checked that it can
be recognized by the host machine
In order to let the USB memory device be recognized in service mode, create an
empty folder on the USB memory device and name the folder with the same name
used when registering the system software for this machine using the SST.
E.g.: iAC5255
1) Service mode (Lv1) > COPIER > FUNCTION > SYSTEM > DOWNLOAD > OK
Connect the USB memory device where system software of the model to be
connected is stored.
2) The download Mode (USB) will appear on the touch panel. Press the [5] key on
the Control Panel.
3) The Backup Menu (USB) will appear. Press the [7] key.
4) Press the [0] key to confirm, and then the SRAM data is stored in the USB
memory device.
5) Press the [C] key to return to the download Menu (HDD).
6) Press the [Reset] key to shut down the host machine.
Temporarily backing up SRAM data to an HDD (only when the HDD Data
Encryption Kit is not installed):
1) Service mode (Lv1) > COPIER > FUNCTION > SYSTEM > DOWNLOAD > OK
2) When the download Menu (HDD) appears, press the [5] key on the Control
Panel.
3) When the Backup Menu (HDD) appears, press the [6] key on the Control Panel.
4) Press the [0] key to confirm, and then the SRAM data is stored in the internal
HDD.
5) Press the [C] key to return to the download Menu (HDD).
6) Press the [Reset] key to shut down the host machine.
At replacement Replace the part from the old PCB to the new PCB.
• 2 boards of DDR2-SDRAMs (3 boards when the option DDR2-SDRAM is
installed)
