The printer stores data such as User-defined character, downloaded character, optional font, routine function,
stamp and template data into FLASH memory. Of these data, User-defined character, downloaded character,
optional font and template data can be used dedicated memory area. Moreover, FLASH memory has shared
memory area as 256K byte user area for routine function and stamp.
Data except template data stored into FLASH memory is used when that is not present into extended RAM.
If data is present in both of FLASH memory and extended RAM, the printer treats data in extended RAM as
priority.
When allocating memory area for User-defined character or downloaded character in extended RAM, the
printer copies data of User-defined character or downloaded character if those data are present in FLASH
memory.
