3.3.3 Connecting the Power Supply Unit
WARNING:
Be sure to always use the included AC adapter: AC adapter,C1 (model no.: M235B).
Don’t use the PA-#### or PB-#### power supply unit with TM-U210.
Using an incorrect power supply may cause fire or electrical shock.
CAUTION:
When connecting or disconnecting the power supply from the printer, make sure the
power supply is not plugged into an electrical outlet. Otherwise you may damage the
power supply or the printer.
3.3.3.1 Connecting procedure
1. Make sure the printer’s power switch is turned off and the power supply’s power cord is
unplugged from the electrical outlet.
2. Check the label on the power supply to make sure the voltage required by the power supply
matches that of your electrical outlet.
3. Plug the power supply cord into the connector shown below.
Note:
To remove the DC cable connector, make sure the power supply’s power cord is unplugged; then grasp the
connector and pull it straight out.
When you connect the power supply unit to the printer, we recommend to do a self test to
confirm the operation. See “Self Test” (page 3-33) for details.
3.3.4 Connecting an Optional External Buzzer
You can connect an optional external buzzer (model no.: OT-BZ20) to a printer by using a
drawer kick connector in order to set the buzzer to sound by command, or when the printer
performs a specific operation such as when an error occurs or paper is automatically cut. You
can also specify different buzzer sound patterns and amount of repetitions according to the
reason for the buzzer sounding.
