Before Use
Installing the rechargeable battery
Danger
Do not use this printer with any rechargeable battery other than that
specified (BT-100), otherwise a fire or damage may result.
When handling the rechargeable battery, see the instructions in the
Product Safety Guide.
Do not disassemble the rechargeable battery.
The battery connector should not be frequently
unplugged and reconnected, otherwise it may be
damaged or the battery cord may break. The battery
must only be removed when replacing it at the end of
its service life, or when the printer will not be used for a
long period of time.

Insert the connector 1 of the
battery in the direction shown
at right.
Insert the connector fully, without using excessive force.
Pay attention to the battery cord colors and be sure you
insert the connector in the correct orientation,
otherwise it may be damaged.
3
Fit the battery cord into the
groove as shown in the
illustration.
4
Install the battery cover by
sliding it onto the back of the
printer.
6
Be careful that you do not catch the battery connector
cord.
Charging
Use the AC adapter designed specifically for this printer to charge the
battery.
After purchasing this printer, be sure to charge the battery fully before
using it (the charging indicator light lights up in orange while charging).
1
Plug the AC adapter cord into
the printer.
2
Plug the AC adapter plug into
an AC power outlet
(AC 110 V-120 V).
Charging of the Li-ion battery
automatically begins.
The orange charging indicator
light is lit.
When charging is finished, the charging
indicator light goes off.
It takes approximately three hours for the battery to
recharge from a completely empty state to a fully
charged state (with the printer turned off).
Charge the battery in an ambient environment with a
temperature between 5 and 40 °C/41 and 104 °F.
(The battery will not recharge if the ambient
temperature is outside this range.)
If the temperature moves out of the above range du
the charging process, the charging stops and the
charging indicator light goes off.
ring
When you use the printer with Bluetooth, we
recommend turning off the power during the charging
process. When the printer enters Bluetooth sleep
mode, the sleep mode continues to consume battery
power even after battery charging has finished and the
battery is fully charged.

After charging is finished, disconnect the AC adapter.
The printer cannot be operated solely with the AC
adapter. The rechargeable battery must be installed.
Indicator lights
A blue or green status indicator light indicates the printer
is operating correctly, while a red light indicates an error
has occurred.
When the status indicator light is green, only the USB
interface can be used. When the light is blue, the Bluetooth and USB
interfaces are available for communication; however, when a
connection has been established using one of the interfaces, data
cannot be received using the other interface until printing has
finished.

Charging indicator light
Yo u can check the status of the power supply by
observing the charging indicator light.
The charging indicator light has two functions.
1 Indicating the charging status (when the AC adapter is con-
nected)
Indicator light status Printer status
Constantly lit Charging
Off Finished charging
Flashing Malfunctioning battery
2 Indicating the battery level (while running with the Li-ion battery)
Indicator light status Battery level
Off 60% or more charged
Flashing once Less than 60% charged
Flashing twice Less than 30% charged
Continues to flash three times Almost empty
To increase battery lifetime, try to discharge the battery
completely before recharging it.
Wait until the light continues to flash three times before
recharging the battery.
Due to the characteristics of batteries, even though the
battery is fully charged, using them in low temperature
locations greatly reduces the number of printouts that
can be made.
In order to maintain the efficiency and life of
rechargeable batteries, remove the AC adapter from
10
the printer when charging is completed.
Storing the rechargeable battery in a location exposed
to high temperatures will cause it to deteriorate. Do not
store the battery in a location exposed to direct sunlight
or high temperatures (such as inside a vehicle, near a
heater, or on a heated carpet).
