[5] BACKUP
But You cannot use this function when there is HDD Encryption Board. Perform any of the following methods.
a) Back up contents of the SRAM by SST; and re-after board exchange; store it.
Refer to "SRAM backup method when there is HDD Encryption Board".
b) Back up contents of the SRAM by USB memory; and re-after board exchange; store it.
Refer to "Backup SRAM of Main controller PCB 2 by USB memory".
c) Like before, You back it up in a procedure as follows.
Be sure to get an approval from the user beforehand.
c-1) Backup the Settings/Registration data
Use the Remote UI.
Management Settings> Data Management> Import/Export

Target data | User | Service
Forwarding Settings | Remote UI (Import/Export) | SST(Sramimg)
Settings/Registration (Except Paper Type Management Settings) | Remote UI (Import/Export)
Mail Box Memory RX Inbox Confidential Fax Inbox | Remote UI (Back Up/Restore Settings)
Form for Superimpose Image | Remote UI (Back Up/Restore Settings)
Auto Adjust Gradation | Enforcement of Auto Adjust Gradation
Key information to TPM to use for coding | Settings/Registration> Management Settings> Data Management> TPM Settings
Service mode MN-CON Settings | None

c-2) Printing the Settings/Registration data by using the service mode.

List of the set/registered data which cannot be backed up is printed.
SRAM backup method when there is HDD Encryption Board:
With SST Ver.4.41or later, obey steps to upload the description of SRAM (Sraming.bin).
Single> Upload Data> Sraming.bin> Save
Data in the HDD is encrypted when the HDD Encryption Board is installed.
For Main Controller PCB 2 to access to data in the HDD, the file description of the Encryption key of the HDD Encryption Board needs to be the same as that of SRAM on Main Controller PCB 2; otherwise, Main Controller PCB 2 cannot access to the data in the HDD and this causes failure in startup of the machine.
Replacement of the HDD Encryption Board / Main Controller PCB 2
Inconsistent the description between SRAM on Main Controller PCB 2 and the encryption key file of the HDD Encryption Board.
Replacement with a new HDD
There is no system data in the HDD
With SST Ver. 4.31 or before, it was necessary to format the HDD (Format ALL), and then install the system (Download the system software) in any case.
With SST Ver.4.41 or later, if the description of SRAM (Sraming.bin) on Main Controller PCB 2 is kept in the PC, you can restore Sraming.bin on Main Controller PCB 2 by using SST after holding down 2 and 8 to start the machine.
When the description of SRAM can be restored, it means that the file description is the same as that of the encryption key of the HDD Encryption Board, which enables access to the HDD. Therefore, you do not need to format the HDD or install the system.
Backup SRAM of Main controller PCB 2 by USB memory:
Prepare for:
USB memory storage device, which the system software for this machine is stored.
or the USB memory recognize it in the Host machine.
On USB memory, You make the blank folder of the same name (e.g.: iA4045) to recognize USB memory on a service mode when You registered a system software for Host machine by SST.
