3.6 EEPROM Data Setting3.6.1 EEPROM data setting modeThe required EEPROM data is set in this mode when replacing the control PCBassembly 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 theprinter base unit (including the waste ink absorber).a) When replacing the control PCB assemblyBefore installing a new control PCB assembly, visually check the waste ink amountfor the waste ink absorber in the printer base unit. After replacing the control PCBassembly, 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 data1. Remove the lithium ion battery.2. While holding down theRESUME button, insert the DC plug of the Universaladapter into the printer.3. While holding down theRESUME button and theCARTRIDGE button, press thePOWER button. Release all the buttons when one long and short beeper sounds.Press theCARTRIDGE 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 inkabsorber).If 25%, 50% or 75% is selected:Press theRESUME button to set data in the EEPROM.After setting is completed, press thePOWER button to turn off the printer.If 0%(EEPROM clear)is selected:Press theRESUME button. Initialization starts and a beeper sounds.To clear the data in the EEPROM, press thePOWER button to turn off the printerand remove the DC plug of the Universal adapter from the printer's power connectorafter completing initialization.Clear the data in the EEPROM.3-23BJC-50Part 3: Operating InstructionsBeeper7 times16 times15 times14 timesWaste ink amount (Use theCARTRIDGE button to change)0% used (new ink absorbed/EEPROM clear)25% used50% used75% used
