MEMO: Image memory (DDR-SDRAM)
The machine is equipped with the following image memory:
capacity: 1 GB
quantity: 1 pc.
Use one of the 2 slots. There is no optional memory for expansion.
1) Turn on the power. If there is a backup of the SRAM data (i.e., if down-
loaded using the SST), upload it.
2) Execute the following service mode item:
COPIER > FUNCTION > CLEAR > CA-KEY (Level 2)
3) Turn off and then on the power.
MEMO:
Execution of the following may delete the keys/certificates used for encrypt-
ed communications and the CA certificates used for authentication of exter-
nal server certificates:
- replacement/formatting of the HDD
- replacement of the main controller PCB/initialization of the RAM
If a key/certificate for encrypted communications has been deleted, the con-
trol 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
TION>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.
Points to Note When Fitting the Security Expansion Board
Whenever possible, do not replace the main controller PCB as part of the
troubleshooting work conducted in relation to the installation of the security
expansion board (option).
The machine checks the compatibility between the HDD and the main con-
troller PCB when a security expansion board is installed. Replacement with
a new board will cause the formatting of the HDD to start automatically, thus
deleting all user data.

When Replacing the Main Controller PCB
- Explain to the user that all user data will be deleted.
- As necessary, ask the user to make a backup of those data items that permit
making of a backup.
- Explain to the user that the following data items do not permit making of a
backup, and require remedial action:
<Suggestions for Remedial Action>
- for mode settings stored using the copy/Box function, ask the user to newly
enter the settings.
- for read mode settings stored using the transmission function, ask the user
to newly enter the settings.
- for files that are yet to be transmitted (i.e., files for selected timer transmis-
sion or reserved for transmission), ask the user to newly transmit them.
- for registered forms used in image synthesis, ask the user to newly enter
them.
- for MEAP applications, ask the user to newly install them.
- for MEAP SMS (service management services) passwords, access the fol-
lowing: http://<iR IP address>:8000/SMS. (Use the factory password
"MeapSmsLogin" (case-sensitive) to log in and change the password.
- for job histories, if a record is needed, ask the user to store away the history
using a remote UI. (However, there is no way of
returning the history to the HDD.)
- for key pairs and server certificates, if the user has added any, ask for re-
installation.
