D. Emergency update (incase of an HDD
breakdown)
The HDD of this machine stores the main program along with the
sophisticated variations.
When, therefore, the HDD breaks down, or when the HDD must be
replaced with another HDD, or when the main program is damaged
by turning OFF the power during the firmware updating, the firm-
ware (main program) must be rewritten into the HDD by the follow-
ing procedures. It is called the emergency update.
[Conditions where the emergency update is required]
The emergency update is required in the following cases:
1) "Main Program Error" is displayed on the panel.
It means that the data are destroyed and that replacement of
the HDD is not required. The problem can be settled by execu-
tion of the emergency update only.
2) "HDD Trouble (E7-03)" is displayed on the panel.
It means a HDD breakdown. The HDD must be replaced with a
new one, and the emergency update must be executed.
* When U2-05 (HDD/EEPROM/SRAM abnormality) or U2-50
(HDD data abnormality related to IMS) occurs, execute SIM16
only, and there is no need to execute the emergency update.
[Environment necessary for the emergency update]
1) The MFP with the HDD where the firmware is rewritten
2) The USB memory which stores the firmware for the emer-
gency upgrade.
File name: emupdate_J2.sfu
* The firmware must be stored in the root folder of the USB
memory.
[Emergency update procedures]
