Notes on Using the Rechargeable Li-ion Battery
Fully charge the battery before use. Do not use it before it is fully 
charged.
High density (dark) printing discharges the battery faster than low 
density printing.
Adjust the print density setting in the printer driver’s dialog box or Printer 
Setting Tool (see the Online User’s Guide).
The battery charging must take place in 32°F - 104°F (0°C - 40°C) 
environments, otherwise the battery will not be charged, and the 
STATUS indicator will remain lit.
If you use the printer when both the battery is installed and the AC 
adapter or car adapter is connected, the STATUS indicator may turn off 
and charging may stop even if the battery has not been fully charged.
Rechargeable Li-ion Battery Characteristics
To ensure the highest performance and longest life from your the battery:Do not use or store the battery in a location exposed to extreme high or 
low temperatures as it may discharge more quickly. This may happen 
when using a rechargeable Li-ion battery with a high charge (charged 
90% or more) in a location exposed to high temperatures.
Remove the battery when storing the printer for long periods of time.
Store batteries with less than a 50% charge in a cool dry place out of 
direct sunlight.
Recharge the battery every six months if it is stored for long periods of 
time.

							Paper Problems

Pages Do Not Print
Pages Are Partially Printed
Indicator Warnings
ProblemSolution
The POWER indicator 
does not lightThe printer is receiving no power.If you are using AC or DC power, connect the 
AC adapter or car adapter correctly and turn the 
AC or DC power outlet on.
If you are using a rechargeable Li-ion battery, 
make sure the battery is firmly installed in the 
printer and is fully charged.
Received data in bufferPrint data is saved in the buffer. If the printer 
recieves incomplete data (for example because 
of a lost Wi-Fi connection), printing will not start.
Turn the printer off, and then turn it on again.
Head or motor is cooling 
downThe thermal head or motor is too hot.Head: The printer stops and resumes printing only 
after the thermal head has cooled down. The 
head may become too hot if you are printing a 
large number of documents with high text 
content. 
If the thermal head becomes too hot, it may 
produce imaging on the paper in areas not 
intended to be printed. To avoid or delay 
overheating, use a lighter density setting, 
reduce the amount of black space being printed 
(for example, remove background shading and 
colors in graphs and presentation documents), 
and make sure the printer has adequate 
ventilation and is not located in an enclosed 
space.
Motor: Continuously using the printer will cause the 
motor to heat up. If it becomes too hot, in this 
case, the printer will stop and resume printing 
after the motor has cooled down.
Data reception errorWith unstable communication, it may not be 
possible to receive data correctly. Improve the 
communication conditions, and then establish 
the connection again.
Printer is in boot modeTo resolve the issue, contact your Brother 
dealer or Brother customer service for 
assistance.
Troubleshooting
ProblemSolution
The paper is jammed in the 
printerSee Clearing a Paper Jam.
The paper feeds through 
the printer, but nothing 
appears on the paperMake sure you are using thermal paper.The print surface must face the back, when 
looking from the front of the printer.
The paper does not feed 
even though the motor is 
runningThe release cover must be completely closed.You must use genuine Brother thermal paper. 
Other paper may not feed through the printer  
correctly.
If you still have problems, the printer may be 
damaged. Contact your Brother dealer or 
Brother customer service for assistance.
ProblemSolution
The image is compressed 
and stretched in many 
placesMake sure the release cover was not left open 
during printing. If it is open, close it completely.
You must use genuine Brother thermal paper. 
Before loading paper, make sure it is not 
wrinkled.
NOTEThis condition may occur more often when 
the printer is used at high altitude (more 
than 10,000 ft (3,048 m)) due to a lower air 
density available to cool the printer.
ProblemSolution
The DATA indicator 
remains lit in green but the 
printer does not printPrinting of all received data is not completed. 
Wait until it is finished.
If paper is not loaded, load the paper.
If the printer does not print even though 
paper is loaded, remove the paper, and then 
load it again.
Try printing again after turning the printer off, 
and then on again.
There may be problems with sending simple 
ASCII text data to the printer. If the CR/LF 
command is not at the end of lines or the 
form feed command is not at the end of the 
last line, the printer may be waiting for this 
data to be sent. Print another page, or press 
the 
 (Feed) button to feed the paper.
The printer may have been started up in 
mass storage mode (see the Online User’s 
Guide for more information). Turn the printer 
off, and then turn it on again.
The application should be 
sending data to the printer, 
but the DATA indicator 
does not light in greenWith a USB connection:
1 Connect the USB cable firmly and correctly.2 Try using another USB cable.With a Bluetooth connection (PJ-762/
PJ-763/PJ-763MFi only):
1 Check that the  (Bluetooth) indicator is lit in blue. If the  (Bluetooth) indicator is flashing or turned off, the Bluetooth connection is not 
established. To establish a Bluetooth 
connection, refer to 
Connecting Using Bluetooth (PJ-762/PJ-763/PJ-763MFi only).2 Specify the correct Bluetooth settings in the 
Printer Setting Tool (see the Online User’s 
Guide for more information).
With a Wi-Fi connection (PJ-773 only):
1 Check that the  (Wi-Fi) indicator is lit in blue. If the  (Wi-Fi) indicator is flashing or turned off, the Wi-Fi connection is not 
established. To establish a Wi-Fi 
connection, refer to 
Connecting Using 
Wi-Fi® (PJ-773 only).2 Specify the correct Wi-Fi settings in the 
Printer Setting Tool (see the Online User’s 
Guide for more information).
ProblemSolution
The DATA indicator turns 
off while a page remains in 
the printerThe computer or mobile device may not have 
sent a full page of data. Try printing the 
document again.
The computer or mobile device may have sent 
the wrong page size information, or the size of 
the loaded paper is wrong.
The printer ejects a 
partially printed page, and 
the DATA indicator 
remains lit or flashing in 
greenUse the correct paper size setting.
NOTEIf the printer is connected via Wi-Fi 
(PJ-773 only), the connection is lost when 
the printer is turned off. When the printer 
is turned on again, it will take up to 15 
seconds for Wi-Fi to become functional. 
						

							Cleaning the Platen Roller
Dirt and debris on the platen roller can cause the paper to be fed incorrectly 
(skewing the print image) and degrade the print quality (distorting the print 
image).
Follow the procedure below to clean the platen roller:
1.Turn the printer on and make sure no paper is loaded.
2.Insert the cleaning sheet into the paper input slot. The text “CLEANING 
SHEET” should be upright and face the front of the printer, as shown. 
The roller will pull the cleaning sheet into the starting position.
3.Remove the backing paper on the upper half of the cleaning sheet, as 
shown.
4.Press the  (Feed) button for more than two seconds. The printer will feed and eject the cleaning sheet.
Cleaning the Printer’s Surface
To clean the printers surface, wipe it with a dry cloth.Do not use a wet cloth or allow water to enter the printer.Do not use benzene, alcohol, paint thinner, or cleaners that are abrasive, 
alkaline, or acidic. Such cleaners may damage the printer’s surface.
This feature is used to print a Letter-size report without connecting the printer 
to a computer or mobile device. (The report will fit on A4-size paper.)
To print the printer settings report:
1.Turn the printer on and make sure no paper is loaded.
2.Press and hold the  (Feed) button until the DATA indicator lights in red.
3.Insert a piece of genuine Brother thermal paper into the printer’s paper 
input slot. The report will print automatically, and then the printer will 
return to idle mode.
