Do not loosen the fixing screw on the inlet guide,
as you will have to adjust the position of the inlet
guide if you remove the inlet guide base. If you
must loosen it, be sure to adjust the position of the
inlet guide afterward by referring to the index on
the fixing assembly.

14.7.1 After Replacing the Hard Disk
0010-9327
1) Formatting the HDD
Start up the machine in safe mode (i.e., turn on
the main power while holding down the 2 and 8
keys).
Using the HD formatting function of the SST,
execute full partition formatting. (For details,
see the chapter on upgrading.)
2) Downloading the System Software
Using the SST, download the following:
System, LANG, RUI, PS-FONT, OCR
dictionary, SSL encryption key, SSL CA
certificate, MEAP content.
3) Execute the following service mode item:
COPIER > FUNCTION > CLEAR > CA-KEY
(Level 2)
4) 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.

data)
If possible, perform the following:
- Using the SST, download the data stored in the
RAM of the main controller.
- Print out the user mode/service mode data.
- If you are replacing the main controller PCB, be
sure to physically transfer the following from
the existing to the new PCB:
[1] BootROM
[2] HDD
[3] image memory (DDR-SDRAM)
[4] counter memory PCB
F-14-36
MEMO: Image memory (DDR-SDRAM)
The machine is equipped with the following im-
age memory:
capacity: 1 GB
quantity: 1 pc.
Use one of the 2 slots. There is no optional mem-
ory for expansion.
1) Turn on the power. If there is a backup of the
SRAM data (i.e., if downloaded using the
SST), upload it.
