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 is minimized, especially while in operation. 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, the printer must be turned off and on again, in order for 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. This paper jam may occur while replacing paper or if
there is vandalizing of the paper exit. However, 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 by command the retractable function in the presenter. If this feature is enabled, after a full
cut command the presenter will push the paper and return it to its sensor. As a default, if the paper remains
above the sensor during 10 seconds, the presenter will pull the paper automatically. The retractable time can
also be programmed by command. To enable the retractable function or change the retractable time, please
refer section COMMAND TABLE (Operation). The printer is prepared mechanically to pull the paper without
any receipt jam.
Reliability of presenter operation without the recommended paper is not guaranteed.
