Priority
*1
Charging battery 
temperature error
*2
The printer suspends 
charging because the 
battery pack temperature is 
out of the operating 
temperature range 
(charging). 
The printer automatically resumes 
charging when the battery temperature 
is within the operating temperature 
range (charging).   
Wait for a while in the place where the 
ambient temperature is 0°C to 40°C 
(32°F to 104°F).

Connected to AC adapter 
only / car charger only
*2
(Battery pack is not 
installed)

Paper cover open error  The paper cover is open.  Close the paper cover.  3 
Voltage error 
The battery pack voltage is 
out of the allowable range. 
Charge the battery pack.  4 
Head temperature error 
The thermal head 
temperature is out of the 
operating temperature 
range. 
The printer automatically recovers 
when thermal head temperature is 
within the operating temperature 
range.   
Wait for a while in the place where the 
ambient temperature is -20°C to 55°C 
(-4°F to 131°F). 
5 
Battery temperature error 
The battery pack 
temperature is out of the 
operating temperature 
range (printing). 
The printer automatically recovers 
when the battery temperature is within 
the operating temperature range 
(printing).   
Wait for a while in the place where the 
ambient temperature is -20°C to 55°C 
(-4°F to 131°F). 
6 
Battery error 
There is an abnormality in 
the battery. 
Remove the battery pack from the 
printer and install it again. When the 
terminals are dirty, clean them using a 
dry, soft, and lint-free cloth.   
If the problem is unsolved, replace the 
battery pack.

  *1: This indicates the priority when multiple errors occur simultaneously. The bigger number indicates higher priority.   
    For example, when "Output buffer full" and "Out-of-paper" occur simultaneously, the LED shows "Out-of-paper" which has the   
    higher priority.
