Error message
Error message
NOTES:
1. When an error occurs, the printer stops and never recovers unless the power is turned off and on.
2. After a write error occurs, turning the printer off and back to on causes "DOWNLOAD MODE" to be displayed
and the printer to enter the download mode. The program needs to be downloaded again.
3. While "DOWNLOAD MODE" is displayed, the expansion I/O output status becomes indefinite.
4. When there is a difference in the model name between the boot program and the actual printer, "MODEL
TYPE ERROR" is displayed and the printer stops with error.
5. When the checksum for the boot program does not end with "00H", "CHECKSUM ERROR" is displayed and
the printer stops with error.
6. After receiving the all data of the boot program, the printer compares it with the currently installed boot
program, and erases the flash memory for writing data if there is a difference.
When there is no difference, the downloading normally ends without erasing the memory or writing data.
7. The LCD may show the message "Initializing..." when the printer is turned off in the download mode. This
does not affect the printer operation.
8. Holding down the [FEED]+[RESTART]+[PAUSE] keys at the timing of printer reset, initiated by executing the
reset function in the system mode or user system mode, causes the forced download mode display to appear
on the LCD. This menu is not executable. The printer must be turned off and back to on while the
[FEED]+[RESTART]+[PAUSE] keys are held down.
