1.3.25 Updating of Head Property Data and Backup/Restoration of Head Calibration
Data
(Maintenance mode 68)
< Function >
Maintenance mode 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 keep the print quality, the machine optimizes the drive conditions of individual head/carriage
units according to the head property data.
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 head/carriage unit.
If you replace the head/carriage unit, you need to enter its property code printed on the property
label (pasted on the new spare part).
Backing up the head calibration data and restoring it
This 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 >
Head Property Data Updating 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 pasted on a new head/carriage unit and enter the property code.
The code to be entered is 10 digits excluding the heading "ALR."
Tip:
Opening the scanner cover when the machine is on standby and holding down the
X
key for at least 5 seconds moves the head/carriage unit to the center of its travel. This
makes it possible to check the property label through the opening.
(4) After entry of 10-digit code, press the
SET
key.
The machine displays the "INPUT ACCEPTED" on the LCD, writes the entered property
code into the EEPROM, and then returns to the initial stage of the maintenance mode.
Note:
If the entered data contains any checksum error, the machine shows the "Input Error"
and becomes ready to accept entry. Go back to step (3).
