Connecting The Optional External Buzzer; Connecting Procedure - Epson TM-T20III Technical Reference Manual

Connecting the Optional External Buzzer

When the optional external buzzer (model: OT-BZ20) is connected to the drawer kick connector of the printer,
you can set the printer so that it beeps when you send commands, when an error occurs, when executed auto
cutting, and when detected paper end. Settings for sound patterns and frequency depending on the occasions
the buzzer beeps are also available.
Use the TM-T20III Utility to make the buzzer settings: enable/disable setting, sound pattern setting, and
frequency setting.

The optional external buzzer is recommended to be installed in the following positions.
• When using the printer horizontally: either side
• When using the printer vertically or on a wall: either side/top/bottom (only for wall hanging installation)
