iR3225 / iR3225N / iR3235 / iR3235N / iR3245 / iR3245N
1) Replace it to the HDD with service setting, and turn on the power
of the host machine.
The machine starts writing the system software on each area of HDD and the
writing progress is displayed on a control panel.
2) When writing is complete, follow the instruction to shutdown.
3) After replacing with the HDD set as Service Parts, start the host machine
in safe mode (by pressing the 2 + 8 keys to turn on the main power
switch).
4) Downloading the system software
Download the system software that has been installed on the HDD before
the replacement using SST (SYSTEM/LANGUAGE/RUI/MEAPCONT/
TTS/ASR/TSTAMP/BROWSER/HELP/MEDIA/WebDAV/SDICT/
KEY).
It may take approx. 5 min to start the host machine after downloading.
5) Follow the message on a control panel and press [Reset] to perform the
down sequence.
6) Turn ON the main power.
7) Execute the following item in service mode;
COPIER > FUNCTION > CLEAR > CA-KEY (level 2)
8) Execute shutdown and turn off/on the main power switch. (The main
power switch is automatically turned off when the shutdown process is
executed.)
14.5.2 After Replacing the Main Controller
0019-8414
iR3225 / iR3225N / iR3235 / iR3235N / iR3245 / iR3245N
1) When replacing the main controller PCB, transfer the following parts from
the old PCB to the new PCB.
For the replacement procedure, see the description in Disassembly/Assem-
bly.
[1] HDD
[2] Image memory (SDRAM)
[3] Memory PCB
[4] Plate
2) Turn on the power supply. If backing up the SRAM data on the old PCB
is completed (downloading using SST is successful), upload the SRAM
data.
3) Execute the following item in service mode;
COPIER > FUNCTION > CLEAR > CA-KEY (level 2)
4) Turn off/on the power supply.
A test copy that is made right after the toner has been stirred can be soiled
on its back with a small amount of stray toner. The symptom will likely
disappear when 3 or so copies are made.
MEMO:
After the paper is picked up from the cassette 1, blank paper is delivered and
APVC correction finishes automatically. (Paper size inside cassette does not
matter.)
MEMO:
The HDD set as Service Parts contains only the system software to start the
host machine. When replacing with the HDD set as Service Parts, be sure to
start the host machine in safe mode (by pressing the 2 + 8 keys to turn on
the main power switch) and install all system software that have been
installed on the previous HDD.
MEMO:
Execution of the following may delete the keys/certificates used for
encrypted communications and the CA certificates used for authentication
of external server certificates:
- replacement of the HDD
- replacement of the main controller PCB/initialization of the RAM
If a key/certificate for encrypted communications has been deleted, the
control panel screen will indicate a message to the effect that the key has
been corrupted: however, the key/certificate/CA certificate installed at time
of shipment from the factory may be
brought back by executing the following:
COPIER>FUNCTION>CLEAR>CA-KEY. If doing so has failed, use the
SST to install the key/certificate/CA certificate, and execute CA-KEY once
again.
Points to Note When Executing Service Mode Item CA-KEY
If the user has generated/added a key/certificate/CA certificate on his/her
own, executing CA-KEY will also delete these files. Inform the user of
this, and ask him/her to re-install them as necessary after the execution of
CA-KEY
.
Before Starting the Work (backing up the data)
If possible, perform the following:
- Using the SST, download the data stored in the RAM of the main
controller.
- Print out the user mode/service mode data.
MEMO:
Execution of the following may delete the keys/certificates used for
encrypted communications and the CA certificates used for authentication
of external server certificates:
- replacement of the HDD
- replacement of the main controller PCB/initialization of the RAM
If a key/certificate for encrypted communications has been deleted, the
control panel screen will indicate a message to the effect that the key has
been corrupted: however, the key/certificate/CA certificate installed at
time of shipment from the factory may be
brought back by executing the following:
COPIER>FUNCTION>CLEAR>CA-KEY. If doing so has failed, use the
SST to install the key/certificate/CA certificate, and execute CA-KEY
once again.
Points to Note When Executing Service Mode Item CA-KEY
If the user has generated/added a key/certificate/CA certificate on his/her
own, executing CA-KEY will also delete these files. Inform the user of
this, and ask him/her to re-install them as necessary after the execution of
CA-KEY.
