Presenter Operation
The presenter mechanism is responsible for the ejection of the receipts printed by the kiosk printer. It is designed
so that paper jam probability is minimized. However, due to paper feed conditions (wrong paper feeding, paper
wrinkles etc.) paper jam may occur, especially when replacing paper. We may, then, consider the following:
• When a paper jam occurs in the presenter entrance, the paper will not reach the presenter sensor (located in
the presenter cover) – in this case, the kiosk printer goes into error condition, thus requiring manual intervention.
After removing the jammed paper (see “Removing Jammed Paper” on page 13), the printer must be turned off
and on again, in order to the printer to come back on line.
• When the paper jam occurs in the presenter paper exit, the kiosk printer will try to force the paper out for 8
seconds. If that does not happen, the printer will wait for 10 seconds, after which it will try a new paper
presenting sequence. If the second try is not effective, the printer will go permanently in error condition, thus
requiring a manual intervention to remove the paper. Note that this paper jam may occur while replacing paper
or if there is vandalizing of the paper exit. In addition, and in order to prevent that, the presenter has a clutch
device that prevents paper jamming if paper exit is blocked.
Retractable Function
It is possible to set the retractable function by command. If this feature is enabled, after a full cut command the
presenter will push the paper and return it to its sensor. By default, if the paper remains below the sensor during
10 seconds, the presenter will pull the paper automatically. The retractable delay can also be programmed by
command. The printer is prepared mechanically to pull the paper avoiding receipt jam.
Reliability of presenter operation without the recommended paper is not guaranteed.
