Enter to the function setting mode in the following procedures:

    Press the POWER switch(located in left edge) while pressing the FEED switch(located in right edge).

    When starting test print, release the POWER and FEED switches and then press the SELECT switch(located in center).

    The printer prints “* SETTING MODE *” and enters to the function setting mode.

    When the printer enters to the function setting mode, release the SELECT switch.

When the printer enters to the function mode, the main menu is printed first.

    The main menu is shown in the follows:

    MAIN MENU

    0 : SET DIPSW — Performs the DIP switch settings.
    1 : QUIT WITHOUT SAVING — Quits without saving the DIP switch settings.
    2 : SAVE & EXIT — Exits with saving the DIP switch settings.
    3 : LOAD DEFAULT — Loads the default settings of DIP switch.
    4 : VIEW CONDITIONS — Prints out the printer conditions.
    5 : PROGRAM DOWN-LOAD — DO NOT USE.

    Select the desired items through the main menu and press the SELECT switch the number of times corresponding to the items No. and then press the FEED switch once. (i.e., When selecting the “VIEW CONDITIONS”, press the SELECT switch four times and then press the FEED switch once. For “SET DIPSW”, press only FEED switch once from the main menu.)

    The printer confirms the selected menu No. Press the SELECT (=YES) switch when the printed contents are matched with the selected items or press the FEED (=NO) switch when the printed contents differs from the selected items. When pressing the FEED switch, the printer returns to the main menu again.

    Press the FEED switch once after pressing the SELECT switch the times corresponding to the number of DIP switch. (i.e., When changing the DIP switch 3 settings, press the FEED switch once after pressing the SELECT switch 3 times.)

    Each DIP switch configures with 8 bits. When setting “1” to the DIP switch from MSB (8th bit) to LSB (1st bit), press the SELECT switch 8 times. When setting “0” to the DIP switch from MSB to LSB, press the FEED switch 8 times. Any combination of “1” and “0” can be set, by using SELECT (=1), and FEED (=0).

    The printer returns to the main menu after printing the input values.

    The settings are not saved in the memory yet at this time.

    When saving the setting, perform the “2 : SAVE & EXIT” through the main menu.

    When abrogating the settings, perform the “1 : QUIT WITHOUT SAVING” through the main menu.

    The DIP switch settings are valid after resetting the power.

Note: When the “SAVE & EXIT” is not performed, the DIP switch settings are invalid (remain at the previous setting.)
