X: This combination disables the proper printer operation.

NOTES: 1. Some program versions are not released actually.

2.Boot programs V1.1A and V2.0A do not support the SNMP function as they are not able to download this function. Any other functions than the SNMP function are supported.

3.As the SNMP function has been included in the main program V5.0, it is not necessary to download the SNMP program. Even if it is downloaded by mistake or the printer is used with the SNMP program installed, there is no impact on the printer operation.

4.Firmware V5.0 or greater will not work with the MAIN3-R or earlier PC board. The MAIN4-R or greater is required. Be careful of the combination.

			Main PC board
		MAIN4-R or greater		MAIN3-R or earlier
Firmware	Boot	Downloaded normally.		When the boot program is sent to the
	program			printer by the downloader, the printer
	V3.0 or			shows “MODEL TYPE ERROR” on the
	greater			LCD and results in an error.
				When the COM is used as the
				interface, the downloader shows
				“Check Sum Error”. (Then, the printer
				is forcibly shut down.)
				After the printer is restarted, it starts
				up in the previous status.
	Main	Downloaded normally.		When the main program is sent to the
	program			printer by the downloader, the printer
	V5.0 or			erases the Flash ROM and shows
	greater			“FORMAT ERROR” on the LCD.
				When the COM or LPT1 is used as the
				interface, the downloader shows
				“Erase Error”. Then, the printer is
				forcibly shut down.
				After the printer restarted, it starts up
				in the DOWNLOAD MODE.
				Downloading the main program earlier
				than V5.0 enables a recovery from the
				erroneous state.
