4.1 Notes when service
4.1.1 Other Points to Note
0020-7969
At times, it is a good idea to print out the user data list (network) and the address table list in user mode before initializing the memory (MMI CLEAR) to keep a
backup of the data. (Be sure to obtain the consent of the user before doing so by explaining its importance.) If it is possible to use an RUI, the data may be exported
for a backup, thus facilitating restoration work. If the user is using multiple iR machines, it may also be a good idea to make use of 'Device Information Delivery
Settings', which is a newly available mechanism.
4.1.2 Recommended setting of system management information
0020-7970
When multiple users use an iR host machine, it is necessary to advise each user to set the system management information.
Setting ID and password of system administrator on the operation unit under (Initial setting/Registration) > [System management setting] > [Setting of system ad-
ministrator's information] has an effect of restraining the third person from falsifying information, for the ID and password are required when a user carries out an
important setting of the iR host machine.
Under the environment that the setting is not done, if a user who does not sufficiently know operation situation of the iR tries to change the setting, following troubles
may occur.
- When the user changes [User ID Management] from [off] to [on], copying operation cannot be done unless ID and password are input.
- When each setting is changed on the network from RUI, that enables to falsify data of address book or delete log.
- When TCP/IP fixed address is changed on the network setting, printing operation via network cannot be done until the port setting is changed.
- When usage restriction of USB device is changed to [on], printing operation via USB becomes disabled.
4.2 Reference matter in market service
4.2.1 Invalidating the License for Transfer to a Different Device data recovery method
0020-7971
Here the keys required to invalidate the license for transfer to a different device will be described. The following is not an explanation of how to validate such license.
'Invalidating the License for Transfer to a Different Device' can be executed in the Service Mode in order to make accessories validated by the license information
available to another host machine.
License history data is required when invalidating the license for transfer to a different device. License history data is stored threefold in 3 different locations - HDD,
Counter PCB, and SRAM on the Main Controller.
Once the HDD and / or Main Controller are replaced with new ones, it may not be possible to invalidate the license for transfer to a different device for options
validated by the license information.
License key history data
License history data is used in order that the transferred license key cannot be used in the same iR host machine again.
-License history data has a total of the number of the iR accessory license key and the MEAP applications and only 30 of the total are doubly stored in HDD and
the counter board.
-Only 30 of the total are doubly stored. The rest is stored in HDD only.
When HDD is broken
If turning on the power of the iR host machine after the replacement of HDD, max. 30 items of license key/transferred license key history data are automatically
recovered in HDD from the license key history data on the counter board.
Lost license key history, which has been stored only in HDD, becomes as follows:
-The transfer license key cannot be issued to unrecoverable license key history.
-The transfer license key for unrecoverable license key history of the license key that the transfer license key has been issued is not displayed in service mode.
When Counter board is broken
If turning on the power after the replacement of the counter board due to the breakage,
following operations are performed.
-Automatically recovered from the SRAM on the main controller board.
-If it is impossible that the history is automatically recovered from SRAM to the counter board, the license key/transfer license key history data is automatically
recovered to the counter board from the license key history data on HDD.
When HDD and Counter board are broken
Recover the data from SRAM to the counter board. Then, recover the data from the counter board to HDD.
When the data cannot be recovered from SRAM to the counter board, all history data of license key/transfer license key will be lost.
The accessories continue to be available even in such cases, although 'Invalidating the License for Transfer to a Different Device' cannot be executed.
4.2.2 Conditions for Using the RUI
0020-7972
For the RUI to be used, it is important that the following be true:
Additional Function>System Settings>Remote UI>ON
Additional Function>System Settings>Network Settings>TCP/IP Settings>Use HTTP>ON
Additional Function>System Settings>MEAP Settings>Use HTTP>ON
Additional Function>System Settings>Network Settings>TCP/IP Settings>IP Address Renge Settings
The address range must permit the use of '127.0.0.1'.
4.2.3 Creating SSL Key-Pair and Server Certification
0020-7975
When exchanging data between MFP machine and PC/Server, it enables setting to execute encryption by SSL (Secure Sockets Layer).
When executing SSL, it needs to generate key-pair and server certification with MFP machine.
By applying SSL, the following functions are available:
- Remote UI
- IPP Print Settings
- Device Information Delivery Settings
- Dept. ID Management Password Confirmation
- E-Mail/I-Fax: Authent./ Encryption Settings
Additional Functions > System Settings > Network Settings > TCP/IP Settings > SSL Settings
