An optical paper low sensor is mounted at the main assembly plate behind the paper roll. The sensor changes its state when there are about 150—200 tickets left on the roll. Rather than using the optical near end sensor, it is possible to use an internal ticket counter and enter the amount of printed tickets after which an alarm or warning should be generated. An out-of-paper sensor is built into the thermal printer.
