3.6 EEPROM Data Setting

3.6.1 EEPROM data setting mode

The required EEPROM data is set in this mode when replacing the control PCB
assembly or the printer base unit (including the waste ink absorber).
The EEPROM (IC14) on the control PCB assembly contains machine specific data,
such as waste ink amount and the remaining quantity of ink in the ink cartridge.
Data must be set in the EEPROM when replacing the control PCB assembly or the
printer base unit (including the waste ink absorber).
a) When replacing the control PCB assembly
Before installing a new control PCB assembly, visually check the waste ink amount
for the waste ink absorber in the printer base unit. After replacing the control PCB
assembly, set the waste ink amount in the EEPROM.
b) When replacing the printer base unit (including the waste ink absorber)
Set 0% (EEPROM clear) after replacing the printer base unit.

3.6.2 Setting EEPROM data

1. Remove the lithium ion battery.
2. While holding down the RESUME button, insert the DC plug of the Universal
adapter into the printer.
3. While holding down the RESUME button and the CARTRIDGE button, press the
POWER button. Release all the buttons when one long and short beeper sounds.
Press the CARTRIDGE button to select the following number of beeper sounds.
Set the waste ink amount of the waste ink absorber in the printer base unit
(Roughly estimate the amount of ink absorbed on the surface of the waste ink
absorber).
Beeper
7 times
16 times
15 times
14 times
If 25%, 50% or 75% is selected:
Press the RESUME button to set data in the EEPROM.
After setting is completed, press the POWER button to turn off the printer.
If 0%(EEPROM clear)is selected:
Press the RESUME button. Initialization starts and a beeper sounds.
To clear the data in the EEPROM, press the POWER button to turn off the printer
and remove the DC plug of the Universal adapter from the printer's power connector
after completing initialization.
Clear the data in the EEPROM.
