4.1.1 Head Data Writing Operation

Data unique to the specific black and color printhead used in the printer is stored in the EEPROM on the
C184 MAIN board. These values must be written to the EEPROM first when the printhead unit, the printer
mechanism, main board, or EEPROM chip is replaced. However, it is not necessary to write them to
EEPROM again, even if the EEPROM is reset from the control panel.
