counters of print length, and ink cartridge information, is stored in the serial EEPROM.
System information is loaded to the RAM or flash memory as required during operation or for
backup.
The description below explains the information stored in each memory area.
- RAM area: Stores the current system data.
- EEPROM area: Stores the default values of system information at power on.
- Flash memory area: Stores structural data and default data of EEPROM. EEPROM data at
the time of shipping and backup data of EEPROM are stored.
