Flash Memory - Seiko RP-F10 Series Technical Reference

6.2 FLASH MEMORY

The FLASH memory of the printer allows user-defined characters, downloaded characters, optional fonts,
macro function, NV graphics function, downloaded bit image function, User page 1-byte fonts, and User
page international characters to be used. The FLASH memory consists of the following areas.
System area:
Font area:
User area:
The system area is rewritten using commands, such as "Change Function Settings" command (DC2 'k', DC2
'w') and "Save Maintenance Counter" command (GS 'g' '1').
The font area cannot be rewritten through the download mode selection.
The user area can be rewritten using registration commands for user-defined characters, downloaded
characters, optional fonts, macro function, NV graphics function, downloaded bit image function, User page
1-byte fonts, User page international characters, and so on.
The memory capacity of the user area is 1048576 bytes. When using registration commands, it is necessary
to know the remaining memory capacity beforehand. Read this section for the remaining memory capacity.
(1) Memory area
The printer allocates or releases the memory area in order to change the use of the memory in the user
area and its capacity.
Allocating the memory area means that the memory is divided into the specified capacity (bytes) so as
to be exclusively used for a certain function.
And releasing the memory area is to disable the division of the memory that the certain function has
used. The released memory area is not reused until the "Initialize User Area" command (DC2 'R') or
"Defragment User Area" command (DC2 '*' '1') is executed.
When using user-defined characters, downloaded characters, optional fonts, macro function, NV
graphics function, downloaded bit image function, User page 1-byte fonts, and User page international
characters, the remaining memory capacity must not be exceeded.
Moreover, the memory capacities for optional fonts, macro function, NV graphics function, and
downloaded bit image function are limited to the values as follows. When using these functions, do not
exceed the limits.
Optional font
Macro
NV graphics (per key code)
Downloaded bit image
