Confidential
Replacing the paper roll stops the buzzer sound and turns off the
PAPER OUT
LED. Also
pressing the
FEED
button stops the buzzer sound and turns off the
PAPER OUT
LED.
Be sure that the
PAPER OUT
LED goes off when the buzzer sounds is stopped.
For details of the status of the LEDs when a paper end is detected, see the following table:
See Appendix B for more details.
TM-U230 has ESC(A command, which can control the internal buzzer. With this command, TM-
U230 can beep the internal buzzer at the specified interval or beeps when the specified event
(paper near end, cover open, paper end, stop printing, recoverable error or unrecoverable error)
occured.
Note:
• When the internal buzzer is disabled by ESC(A command, the
PAPER OUT
LED does not
light or blink, because the internal buzzer corresponds to the
PAPER OUT
LED.
• The
PAPER OUT
LED blinks correspondingly when the internal buzzer is set to beep if
paper end is detected.
• ESC(A command setting is canceled when the power is turned off.
• Refer to the ESC(A command description in TM-U230 series specification for more
details.
The printer status can be checked by commands such as GS a.
