[8] Rewriting procedure after an error interruption

If errors occur while writing ROM data, it is written the same way as explained in "Writing ROM data newly"
in [3]-2, "Instances of ISW transfer."
- Graphics control program
The timer LED (orange) flashes. (Nothing will appear on the operation LCD because communication with the
operating unit is disabled.)
Retry ISW after turning the main switch OFF, then ON.
- Operation control program
Since the 25 mode is disabled, launch the HELP + CHECK mode to run ISW.
- Other control programs
Relaunch the 25 mode to retry ISW. (It is assumed that the copier has both the graphics control and
operation control programs successfully installed.)
