Chapter 2 Setup
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
autocutting, and when detected paper end. Settings for sound patterns and frequency depending on the
occasions the buzzer beeps are also available.
To enable/disable the buzzer and to set the buzzer sound pattern, frequency, etc., refer to "Software Settings" on
page 65.
Attachment Position
The optional external buzzer is recommended to be installed in the following positions.
• When ejecting paper upward: Right side viewed from the front
• When ejecting paper frontward: Left side viewed from the front, or the top
• Be sure to turn off the printer before you connect/disconnect the optional external buzzer.
• Do not connect both the optional external buzzer and the cash drawer to the printer at the
same time by using a branched connector.
• Do not install the optional external buzzer at the roll paper exit.
• If you are using the Wi-Fi + Bluetooth model, do not install the buzzer on the left side viewed
from the front when ejecting paper upward or on the right side viewed from the front when
ejecting paper frontward. Doing so may interfere with Wi-Fi communication. If you are using the
Standard model, the buzzer can be installed on either side.
• To prevent liquid from entering inside, it is recommended to install the optional external buzzer
so that the volume adjustment knob is positioned sideways or downward.
