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.
4.5.2
Preprinting on printer media
There are a few guidelines that need to be followed to ensure operation:
· Due to the heat developed during printing, the preprint shall meet the
requirements applicable for preprinting on paper intended for laser printing.
OCR-blind ink shall be used.
· Ink used for preprinting on the thermal side shall be non-abrasive.
· The ink shall not smear while wound up on the supply roll, or during the
printing process.
· Ink used for preprinting in the black mark zone and in the centre of the paper
on the non-thermal side shall have no influence on the reflective IR-sensor.
OCR-blind ink shall be used.
