Problem Solution
The POWER indicator does not light The printer is receiving no power.
If you are using AC or DC power, connect the AC adapter or car
adapter correctly (see Connect the Printer to External Power
on page 14) 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 buffer Print data is saved in the buffer. If the printer receives 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 down The 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, the printer will stop and resume printing after the
motor has cooled down.
This 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.
Data reception error With unstable communication, it may not be possible to receive
data correctly. Improve the communication conditions, and then
establish the connection again.
