TM-U230 Developer’s Guide

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 PAPEROUT 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.
