9.1.4.23 Updating of Property Data (Function code 68)
„
Function
To keep the print quality, the controller optimizes the drive conditions of individual head/
carriage units according to the property data. For instance, the controller optimizes the head
drive strength, ink jet-out timing and other drive conditions according to the electromechanical
properties unique to individual head/carriage units and ambient temperature.
The property data is stored in the EEPROM on the main PCB and its property code is printed on
the property labels attached to the machine and the head/carriage unit.
If you replace the head/carriage unit with a new spare part, you need to enter its property code
printed on the property label (that comes with the new spare part) and replace the old property
label on the machine (see
Appendix 1 for the label location) with the new one. If the old part
may be used in future, store the old property label also with the old part.

Operating Procedure
(1) Press the 6 and 8 keys in this order in the initial stage of the maintenance mode. For models
without numerical keypad, enter 6 and 8 in this order using the , and OK keys.
(2) Press the 2 , 5 , 8 , and 0 keys in this order. For models without numerical keypad, enter 2, 5,
8, and 0 in this order using the , and OK keys.
The current property data stored in the EEPROM appears on the LCD and the machine is
ready for entry.
(3) Check the property label that comes with a new head/carriage unit and then enter the
property code.
The code to be entered is 13 digits excluding the heading alphabets.
For models without numerical keypad, to enter numerical codes, press the / key several
times to display the numerical code to be entered and then press the
OK key. Repeat this
operation for each numerical code.
If the customizing code contains letters "A" through "F," on models with a numerical
keypad on the control panel, press the
1 through 6 keys while holding down the # key,
respectively. On models with a touch panel, press the "A" through "F" keys on the software
keypad.
(4) Press the OK key ( Photo Capture key for models without OK key).
The machine beeps (MFC only), shows the "INPUT ACCEPTED" on the LCD, and writes
the entered property code into the EEPROM. Then it returns to the initial stage of the
maintenance mode.
NOTE: If the entered data contains any checksum error, the machine beeps (MFC only),
shows the "INPUT ERROR" and returns to the ready-to-enter state. Go back to step (3).
