1.4.22 Updating of Head Property Data (Maintenance mode 68)
<Function>
To maintain print quality, the machine optimizes the drive conditions of individual Head/
carriage units according to their property data.
Head property data is stored in the EEPROM on the main PCB and its property code is
printed on the head property labels attached to the Head/carriage unit.
If you replace the Head/carriage unit, you need to enter its property code printed on the
new head property label (pasted on the spare part), following the procedure below using
maintenance code 68.
<Operating Procedure>
(1) Enter [6] and [8] in the initial stage of the maintenance mode.
(2) Enter [2], [5], [8], and [0].
The current property data stored in the EEPROM appears on the LCD and the
machine is ready for entry.
(3) Check the head property label pasted on the Head/carriage unit, and enter the
property code.
The code to be entered is 10 digits excluding the heading "ALR".
Tip In the standby state, open the scanner cover, and then hold down [Stop] or [X] five
seconds or longer; the Head/carriage unit moves to the center. Check the head
property label from the opening.
(4) After entering the 10 digits, press [SET] or [OK].
The machine displays "INPUT ACCEPTED" on the LCD and writes the entered head
property code into the EEPROM.
It then returns to the initial stage of the maintenance mode.
Note If the entered data contains any checksum error, the machine shows "Input
Error" and becomes ready to accept entry. Go back to step (3) and re-enter.
