- If the voltage displayed is greater than 18 mV, check that the sensor is properly connected to the
circuit board and that the wire is not broken or crushed along its route to the unit. If everything is OK,
change the sensor.
* Refer to the electronic board connection diagram to identify the faulty sensor.
- If the voltage displayed is unstable, change the sensor.
- If the voltage displayed is preceded by the ‘-‘ sign:
· the measu / - connections on the sensor are the wrong way round

SENSOR DIAGNOSTICS
3.2.3.2 PRINTER SELF-TEST (optional)
Standard self-test ticket
To run a printer self-test, press the paper feed button and, at the same
time, switch the printer on. The self-test starts after the paper feed button
has been held down for a second or two.
Release the paper feed button as soon as the self-test starts.
If the self-test does not run, check that:
. the power supply is OK (adequate voltage)
. the printer is correctly connected to the board (refer to the
electronic board connection diagram).
. If the ticket is identical to the standard ticket, the printer is working
correctly.
If not, check that:
. the ribbon is not worn
. the paper roll has paper left on it
. the paper is being fed through correctly.
