5.8- ERROR PROCESSING

5.8.1- Error types

When an error occurs, the printer visually notifies its type through the LED. This fact allows the
final user to have a direct and visual reference of the current printer status.
On the other hand, the printer status and all its possible errors can also be monitored via software
through the DEL EOT command. In this way, the application developer can have more complete
information on the printer status, therefore being able to act accordingly.
The errors detected by the interface are the following: 'near-end paper', hardware error, power
supply voltage error and printing head temperature error.
When any of these errors happen, the led blinks with a different blinking timing sequence for each
of them. If no error happens the led will light permanently green.

At initialization, the printer internally checks its hardware devices. If they do
not function properly, an error occurs.
This error cannot be recovered. One of the control board components might
be damaged and should be replaced or repaired.
The power supply voltage is out of range (5VDC + 10%).
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.
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.
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
