9.1.4.17 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.

(2) Press the 2, 5, 8, and 0 keys in this order.

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 12 digits

excluding the heading alphabets.

Head property code

To enter letters "A" through "F," press the 1 through 6 keys while holding down the # key,

respectively.

(4) Press the OK key.

The machine beeps, 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, shows the "INPUT

ERROR" and returns to the ready-to-enter state. Go back to step (3).
