Operation Modes
The printer can be operated in the following modes:
Normal (Remote mode)
In this state, the printer is being controlled by the host through the serial or parallel communication interfaces.
Dump mode
In this mode advanced users and programmers can identify communication problems between the host and the
printer or check if a certain programmed data is correctly being sent to the printer, thus being a debugging tool. To
start the hexadecimal dumping, turn on the printer while pressing the paper feed switch. A message will be printed
on the paper asking you to press once more the paper feed switch if Dump mode is desired, as shown:
Self-testing
To run a self-test, turn the printer off. Press and hold the Paper Feed switch and turn it on. When the printer starts
printing, the paper feed button can be released. A message will be printed asking you to wait the self-test. In the
self-test you will find the printer firmware version, among other information.
- Press PAPER switch once for DUMP MODE
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.
