)
Error display Error contents
Error 252 Data protection kit-A1 does not exist.
Error 253 User’s data protection kit-A1 does not exist, but different data
protection kit-A1 is installed with the HDD.
Error 256 Invalid HDD is installed.
Step
1
Re-connect the printer to the user’s data
protection kit-A1 that is connected to the
printer in the very beginning when user starts
using the system.
No ( If user’s data protection kit-A1 that
is connected in the very beginning
does not exist )
Yes
Maintenance is complete.
(User HDD has been removed.)
Step

Does the printer work normally when the
maintenance CU board and the data protection
kit-A1 for maintenance use are installed
instead of original boards?
No
Yes
Maintenance is complete.
(User HDD has been removed.)
Re-setting of IP address and
others are required:
Note 1, 3 and 4
Step
3
Replace the printer. (Analysis is not possible.)
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.
Note3 : Data
protection kit A1 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 : W
hen 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.
