When replacing PWBA MCU with a new one
The life information of the replacement parts, correction parameters, etc are stored in
EEPROM on the MCU board (PWBA MCU). The EEPROM was mounted in IC
socket of the MCU board on previous models, whereas the EEPROM of this product is
soldered directly on the MCU board and it is quite difficult to replace it. Therefore,
when the PWBA MCU is replaced with a new one, the data in the EEPROM must be
backed-up and re-stored to the EEPROM on the new MCU board.
REMOVAL
1.
To enter the maintenance mode, while holding down the [Left(
)], [Up(
)],
[Down(
)] and [Right(
)] buttons, turn the printer on.
2.
Execute the "MCU DATA BackUp" in the maintenance menu to temporarily store
the data stored in the old EEPROM on PWBA MCU.
3.
Remove COVER ASSY LH.
4.
Disconnect all connectors from the PWBA MCU.
5.
Remove the 4 screws (silver, with flange, 6mm) fastening PWBA MCU to the
main unit.
6.
Remove PWBA MCU from the main unit.
C A U T I O N
When the printer is turned on after replacing either the PWBA
MCU or the PWBA CRUM, the information that specific to each
printer unit is automatically stored on a memory of replaced
circuit board. Due to this reason, the board becomes unique to
specific printer unit, and the board is no longer usable on
another printer unit. Do not reuse the board that previously
installed on another printer unit.
When replacing the PWBA MCU, verify that the version of
firmware on new PWBA MCU matches the version of previous
PWBA MCU. If not, be sure to make them matches each other
by either upgrading or downgrading the firmware. Make sure to
execute [MCU Data Restore] in the MAINTENANCE menu only
after matching the firmware version.
C A U T I O N
When printer is in the following condition, [MCU DATA
BackUp] and [MCU DATA Restore] cannot be executed.
During power-save mode
During warming up
During printing
During adjustment
Once the backup has started, do not turn the printer's power off
until the engine stops.
