More information on these errors can be found below:
NEAR-END PAPER ERROR
[Description]
This error happens when the ‘near-end paper’ sensor detects that the paper
roll is close to the end. This means that using a paper roll with an external
diameter of 100 mm and inner diameter of 25 mm, the sensor will trigger the
error when there are still 1.5 meters of paper approx.
This indication should be really taken as a warning, not as an error as such.
The action depends on the application and the developer’s criteria.
[Recover action] Replace paper roll.
[Notes]
When this error happens the printing is not interrupted, although using the
ESC c 4 command could stop it. This error is different from the ‘out of paper’.
HARDWARE ERROR
[Description]
At initialization, the printer internally checks its hardware devices. If they do
not function properly, an error occurs.
[Recover action] This error cannot be recovered. One of the control board components might
be damaged and should be replaced or repaired.
POWER SUPPLY VOLTAGE ERROR
[Description]
The power supply voltage is out of range (5VDC + 10%).
[Recover action] This is a recoverable error. Unplug the power supply from the printer and
check if the output voltage of the power supply is within the specified range.
Replace it in case it is not working properly.
[Note]
When this error occurs, some parts of the printer may be damaged. If this
happens, the printer will be unable to recover itself and some of its
components are likely to be replaced.
THERMAL HEAD TEMPERATURE ERROR
[Description]
Due to very continuous use of the printer or due to environmental conditions,
the temperature in the thermal head may reach levels (above 80ºC), which
can damage the printer itself. When this situation occurs, an error must be
indicated in order to protect the printer from abrasion.
