7. TROUBLESHOOTING PROCEDURE
Specification for safety:
•
If the data protection kit-A3 is removed from printer or swapped by others, it is
informed to user as a warning. (Error processing)
•
Program download and EEPROM read-out are prohibited so that the data
protection kit-A3 works safely.
Consequently
, restrictions that have not been applied are newly added after the
data protection kit-A3 is installed in C830.
•
Normal operation can be performed when the CU board including EEPROM and
the data protection kit-A3 are installed as a pair. (Combination with the PU board
and with engine is not restricted.)
Normal configuration (HDD is not used. Normal HDD is installed)
When the CU board becomes
faulty:
Replace the CU board
(User’s EEPROM should be used.)
When the normal HDD becomes
faulty:
Replace the HDD only.
After the data protection kit-A3 is installed
When the CU board becomes
faulty:
Replace the CU board (EEPROM of the
maintenance board should be used.)
Replacement of the data protection kit-A3 is not
required, but internal data are deleted.
When the data protection kit-A3
became fault:
Replace both of the data protection kit-A3 and the
CU board. (EEPROM of the maintenance board
should be used.)
• After the data protection kit-A3 is installed, the CU board is linked to a specific
HDD. Therefore, the printer cannot be used without the specific HDD.
T
he link can only be cancelled by the Takasaki Design department.
• After the data protection kit-A3 is installed, some of the PJL functions cannot be
used.
- Do
wnloading of all of the F/W (including NIC F/W and PU F/W)
- Read and write of the EEPROM (CU and PU)
Upgrading of PU F/W and read/write of PU EEPROM after the data protection
kit-A3 is installed:
Replace the CU board once with the new CU board in which the data protection
kit-A3 has not been installed before.
Upg
rading of CU F/W
Replace the CU board with new CU board in which the CU F/W is already
upgraded. Data in the data protection kit-A3 will be deleted.
Error processing flow when the error 001-073, -254 has occurred (CU board related error)
Step
1
Does the printer work normally when the CU
board is replaced by the maintenance CU board
? (Be sure to use EEPROM of the maintenance
board. Note 1) (Do not install the data protection
kit-A3)
Yes
No
(Analysis is not possible.)
Replace the printer.
Step
2
Does the printer start up normally when the user’
s data protection kit-A3 is installed?
No
Yes
Maintenance is complete.
(CU board failure) Re-setting
of IP address and others are
required: Note 1 and Note 4
Step
3
Does the printer start up normally when the
data protection kit-A3
of maintenance use is
installed?
No (Error 253 occurs) Note 2
Yes
Maintenance is complete.
(CU board failure, and data
protection kit-A3 failure)
Re-setting of IP address and
others are required:
Note 1, 3 and 4
Step
4
Does the printer work normally when the
maintenance CU board
and the data protection
kit-A3
for maintenance use are installed
instead of original boards?
No
Replace the printer. (Analysis is not possible.)
Yes
Maintenance is complete.
(CU board failure, and data
protection kit-A3 failure)
Re-setting of IP address and
others are required:
Note 1, 3 and 4
Note1 : When EEPROM of user’s board is used, error 253 (HDD unmatch) occurs.
Re-set the user environment such as IP address by using the EEPROM of
maintenance board.
Note2
: If a part of the functions of the data protection kit-A3 that user is using became
faulty, the system can be recovered by using Step 3 if user’s data protection kit-A3
is completely faulty because there is no restriction on combination in this case.
If Step 2 is used, there is a restriction in combination of the maintenance CU
board and user’s data protection kit-A3. Therefore, if different HDD is connected
afterwards, error 253 will be issued.
Note3 : D
ata protection kit A3 after replacing should be collected by either of the following
methods
1
. Disassemble the kit, and deliver only HDD storing user secret data to a user.
2. Take any measures to prevent information leak.
Note4
: When the CU board is replaced, the printer cannot be used without the specified
HDD because the user’s CU board has been linked to the specific HDD. Until the
link is cancelled by design department, it cannot be used. (Situation should be
reported to design department.)
