Updating Of Head Property Data And Backup/Restoration Of Head Calibration Data (Function Code 68) - Brother DCPJ525W Service Manual

1.4.23 Updating of Head Property Data and Backup/Restoration of Head Calibration
Data (Function code 68)
Function
Function 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 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 machine and the head/carriage unit.
If you replace the head/carriage unit, 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
store the old property label also with the old 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.
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 that comes with a new head/carriage unit and then enter the
property code.
The code to be entered is 10 digits excluding the heading alphabets.
Models with numerical keypad on the control panel
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 becomes ready to accept entry. Go back to step (3).
