1.3.25 Updating of Head Property Data and Backup/Restoration of Head Calibration Data
(Maintenance mode 68)
<Function>
Maintenance code 68 provides two types of procedures: one for "updating the head property data"
and the other for "backing up the head calibration data and restoring it".
Updating the head property data
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 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 property
label (pasted on the spare part), following the procedure below using maintenance code 68.
Head calibration data backup/restoration procedures
In maintenance code 68, the procedure backs up the head calibration data into an external memory
(memory card or USB flash memory) and restores it to the machine.
<Operating Procedure>
Updating the head property data
(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) With the scanner cover open, check the property label pasted on the back of the upper cover,
and enter the property code.
The code to be entered is 10 digits excluding the heading "ALR".
Tip The illustration above shows where to affix the head property label.
(4) After entering the 10 digits, press the [SET] or [OK] key.
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.
