3) Turn off and then on the power.
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/formatting of the HDD
- replacement of the main controller PCB/initial-
ization of the RAM
If a key/certificate for encrypted communications
has been deleted, the control panel screen will in-
dicate 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: COPI-
ER>FUNCTION>CLEAR>CA-KEY. If doing
so has failed, use the SST to install the key/certif-
icate/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 nec-
essary after the execution of CA-KEY.
Points to Note When Fitting the Security
Expansion Board
Whenever possible, do not replace the main con-
troller PCB as part of the troubleshooting work
conducted in relation to the installation of the se-
curity expansion board (option).
The machine checks the compatibility between
the HDD and the main controller PCB when a se-
curity expansion board is installed. Replacement
with a new board will cause the formatting of the
HDD to start automatically, thus deleting all user
data.

*1: limited to those settings that may be exported
using a remote UI or transmitted as part of
machine information.
*2: limited to when the MEAP application in
question offers a backup function.
*3: limited to data within the User Box.
When Replacing the Main Controller PCB
- Explain to the user that all user data will be de-
leted.
- 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 transmission 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 following: 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.
