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 during
the charging process, the charging stops and the
charging indicator light goes off.
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.
8

After charging is finished, disconnect the AC adapter.
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.
The printer cannot be operated solely with the AC
adapter. The rechargeable battery must be installed.

direction.
There is no more paper.
Correctly install a paper cassette
containing paper (see page 14).
Remove the paper cassette once, or turn
off and on the printer to clear the error.
A paper misfeed occurred.
Remove the misfed paper
(see page 22).
If you do not remove the misfed paper
after turning off and on the printer, the
error persists.
Clean the paper feed roller and remove
paper powder (see page 21).
A transmission error occurred.
Check the transmission status
(see page 17).
Wait for a few seconds. If the printer has
recovered from the error, resend the data
to resume printing.
If the printer does not recover during a
Bluetooth connection, re-establish the
connection.
An overheat error occurred.
The inside of the printer has started to
overheat.
Wait until it cools down.
If an overheat error has occurred during
the printing process, the paper being

Off Finished charging
Flashing Malfunctioning 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 timesAlmost 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
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).
11
This printer is powered with a rechargeable Li-ion
battery. If the printer can only be used for a short
period of time even though the battery is fully charged,
the battery may have reached the end of its service life.
Replace the rechargeable Li-ion battery with a new
one.
To protect the circuitry, the battery cannot be charged if
the unit is in a location exposed to extremely high or
extremely low temperatures.
Do not wind the AC adapter cord around the adapter or
bend the cord, otherwise the cord may be damaged.

Frequently Asked Questions
I often wound the cable of the charging AC adapter around the
adapter or bent the cable to move the adapter. This often
causes the cable to break and the adapter to stop working.
When carrying the AC adapter,
securely bind the cable using a tie
wrap to prevent any load from being
applied to the cable.
I often carried the printer with the USB cable connected to it.
Doing so caused the USB connector to break and
subsequently there is no USB connection available now.
Disconnect the USB cable when carrying the printer. Even if you
put the printer in a bag, if the USB cable is connected to it, a
large amount of pressure will be applied to the USB connector
when the cable moves inside the bag.
When I left the printer in my car, the printer was affected by the
high interior temperature and became deformed.
Consequently, a malfunction occurred. Furthermore, the
thermal paper turned black.
The temperature inside a car may become extremely high. Do
not leave the printer inside a vehicle.
·
The printer can be used in the following environment:
Te mp e r ature: 0-40 °C/32-104 °F
Humidity: 20% to 80% (Maximum wet-bulb temperature:
27 °C/81 °F)
30
An optional car adapter is
provided but it is only for the
purpose of charging the battery.
Exposing the printer to high
temperatures causes the paper
to become discolored and the
battery to deteriorate. Do not
leave the printer inside a vehicle.
I often pressed the power switch using a sharp object such as
the tip of a pen, which might apply high pressure to the switch.
The switch subsequently broke and did not function from that
point.
Press the power switch with your finger.
I stamped a seal on printed text. The ink did not dry
completely, and printed text was erased when I rubbed it with
my finger.
Stamping a seal on the heat-sensitive surface is not
recommended. In addition, all stamp manufacturers do not
recommend stamping a seal on heat-sensitive surfaces. Make
sure you check this before using stamps. As is the case with ink,
pens or adhesives such as Scotch tape may cause printed text to
be erased.
·
Do not operate or store the printer in a location exposed to
extremely high or extremely low temperatures, extreme humidity,
clogging dust, or extreme vibrations, such as those:
I
nside a vehicle (particularly in a closed car under a hot sun)
Near water, such as in a bathroom or near a water heater,
or in an extremely humid location
In a location where it is exposed to moisture, such as
rain or mist
In an extremely hot location, such as near naked flames,
heaters, or in direct sunlight
In a location where condensation may form
31
Paper cannot be fed, although there is still paper left in the
cassette.
Contamination of the paper feed roller may prevent some sheets
of paper from being picked up.
Use Scotch tape to remove dirt on the paper feed roller.
To increase the life of the Li-ion battery:
·
We recommend discharging the Li-ion battery completely before
recharging it. Avoid recharging the battery frequently before it is
completely discharged.
*
· Storing the rechargeable Li-ion battery in a location exposed to
high temperatures will cause it to deteriorate. Do not store the
rechargeable Li-ion battery in a location exposed to high
temperatures (such as inside a closed car under a hot sun) or
direct sunlight.
·If you do not intend to use the printer for a long period of time,
remove the rechargeable Li-ion battery from the printer, and
then store the battery in a cool, dark place (at a temperature of
20 °C/68 °F or less) to maintain performance. As the battery
discharges naturally, charge it once every three months while
storing it in a cool, dark place. *
* Caution: About the battery level
When the charging indicator light repeats flashing once, the
battery level is less than 30%.
· 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.

32
The AC adapter connector on the printer has broken, and the
battery cannot be recharged.
If you carry the printer
with the AC adapter plug
connected, the AC
adapter connector on the
printer may be damaged.
To prevent this problem,
remove the AC adapter
plug from the connector
whenever you carry the
printer.
Carrying the printer with the AC adapter plug connected will
subject the plug to a periodic force. The force applied to the plug
generates a load on the connector on the printer, and solder in the
connector may fracture and result in disconnection.
As the printer is a precision device, pay careful attention when
removing or inserting the AC adapter plug.
Using paper other than that genuine Brother paper may cause
frequent paper feed errors.
For Brother mobile printers, make sure you use paper supplied
by Brother. If other paper has been used, paper feed failures may
occur frequently, which cannot be solved by cleaning the paper
feed mechanism. For any failures caused by paper other than
Brother paper, you will be liable for repair costs even if the
charge-free warranty period is still in effect.
Incidentally, certain types of paper from other suppliers may not
cause failures.
Handling the paper cassette
The Brother mobile printer determines the paper type depending
on the loaded paper cassette, then automatically selects the
settings appropriate for that type of paper.
Do not transfer paper to a different paper cassette. Do not try to
reuse paper that has already passed through the printer. Doing
so may cause double feeding, empty feeding, or other types of
paper feed errors, or cause a print head failure.

If the printer has been moved to a cool temperature
environment:
The printer may not work when the ambient temperature is lower
than 0 °C/32 °F. In an ultralow temperature environment (at -10 °C/
14 °F or lower), the number of printable pages becomes less.
Print data from the printer in a location with an ambient
temperature of 0 °C/32 °F or higher. If the printer has been moved
to a cool temperature environment, gradually increase the
temperature to be closer to the external temperature to prevent
condensation from forming.
Storing thermal paper
[Storing before printing]
Store thermal paper inside its packaging (protected from light
and air) at an ambient temperature of 25 °C/77 °F and a humidity
of 65% RH or lower. Use the paper within one year after the
purchase date.
[Storing after printing]
Store the (filed or unfiled) thermal paper in a cool and dark
location at 25
°C
/77
°F
or lower.
[Precautions for storage]
•Do not allow the following items to come in contact with the heat-
sensitive surface or back surface:
1)Back carbon and carbonless paper, and diazotype paper
2)Flexible polyvinyl chloride products, rubber mats, rubber
erasers, and other materials containing plasticizer
3)Adhesive tapes, correction fluids, permanent markers, and felt
pens
4)Organic compounds containing alcohol, ketone, ester, or the
ether group
5)Leather products, hand creams, hair products, and cosmetics
• Do not soak the thermal paper in water, sweat, or other
liquids.
• Do not touch the thermal paper with wet or sweaty hands.
• Do not glue the heat-sensitive surface. When gluing the
back surface, use starch, poval, CMC, or other waterborne
adhesives.
34
• When the heat-sensitive surface or back surface is stamped
with a seal, the white heat-sensitive surface will become
discolored or the printed part may fade due to a chemical
reaction with the ink contents.
• Do not scratch the heat-sensitive surface or apply frictional
heat to it.
•Copy your important documents and store the copies
separately.
