Draft document
CHAPTER 1: Set Initial Conditions
Commands
The Set Initial Conditions (SIC) command sets the printer to the default values that
were set at the factory or to user-defined defaults.
The following data is applicable to both IBM and Epson modes, unless otherwise
noted.
The SIC command cannot be used in OKI emulation mode.
There are three copies of the settings for each of the parameters specified by the SIC
command:
•
Factory default settings stored in flash memory
•
User default settings stored in NVRAM
•
Printer's current settings stored in RAM
Factory
Factory defaults cannot be modified.
User
The SIC command has the ability to override Current settings with the
User defaults or Factory defaults.
It can then change those values and
optionally store then back to NVRAM as the new User defaults.
Current
When the printer is turned on, the current RAM settings are initialized
from the User default settings.
The basic commands implemented in
IBM, Epson and Oki emulations can modify the Current settings stored
in RAM but cannot save them back to User Defaults in NVRAM.
