Paper did not enter in the presenter
Presenter can not eject the paper
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.

KF-6580 · Revision 1.2
Operation Modes
The printer can be operated in the following modes:
Normal
In this state, the printer is being controlled by the host through the serial, parallel or USB 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:
- Press PAPER switch once for DUMP MODE
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 waiting for the selftest. In the self-test you will find the printer firmware version, among other information.

Communication InterfacesCommunication Interfaces
Communication Interfaces
Communication InterfacesCommunication Interfaces
Communication between a host and the printer can be performed in three communication protocols: USB, Parallel
or Serial RS-232, according to the printer model.
Communication cables are not supplied with the printer
Serial Interface
The RS232 serial interface uses a female DB-25 connector. The serial port can operate using the DTR/DSR mode,
with 7 or 8 data bits, with or without parity, even or odd parity, one start bit and one or more stop bits. In the RS232
standard, the logic low level corresponds to a +12V voltage level and a logic high level corresponds to 12V.
DTR / DSR mode
In this mode, the printer’s DTR line controls the flow of data sent from the host’s TX line and received by the printer’s
RX pin. In this case, when the printer’s DTR signal is low (+12V) the printer requests the host to send data. When
the DTR signal is high (-12V) the printer tells the host to stop sending data.

Troubleshooting
The following table described some of the problems that might occur while using the printer. For every problem
there is a possible cause described here and a suggested procedure to solve the problem.
Problem Possible Cause Procedure
Check if there is a central switch
for the room / outlets. Connect
some other equipment to the
outlet to check its operation.
Turn off the printer, check the
power cord’s continuity and a
perfect connection between the
printer and the electric outlet.
The printer does not turn on.
There is no power in the
electric outlet.
A problem with the power
cord – it may be broken or not
well connected to the printer
and / or outlet.
The printer does not respond to
the commands sent.
Parallel communication is faulty.
Serial communication is faulty.
The parallel / serial / USB
cable has one or more lines
with faulty connections /
broken wires.
Wrong programming
sequences.
The parallel cable has one or
more lines with faulty
connections / broken wires.
The pin layout does not follow
the Centronics standard.
The serial cable has one or more
lines with faulty connections /
broken wires.
The pin layout does not follow
the correct protocol.
The baud rate is incorrectly set.
Check for a good connection
between the printer and the
host or change the cable.
The programming sequences
can be checked in the dump
mode. Put the printer in dump
mode and run your application
again. The printer will show the
hexadecimal and ASCII codes of
all bytes being received from the
host.
Check for a good connection
between the printer and the
host or change the parallel
cable.
Check the correct pin layout in
this manual.
Check for a good connection
between the printer and the host
or change the serial cable.
Check if the pin layout used
complies with the protocol being
used for data transmission.
Remember that the printer uses
the DTR/DSR protocol.
If the baud rate set on the printer
is different from the baud rate of
the host, the printer will print
random characters or not print at
all. Check carefully the host’s
serial baud rate configuration as
well as the printer’s DIP switch
settings.

Preventive Maintenance
Cleaning the Presenter:
Remove debris and paper dust from the presenter by using a vacuum cleaner, or by blowing or by using a dry soft
brush. Perform this operation when replacing paper roll.
Printer head cleaning procedure
Adhesion of dusts of paper and foreign materials may deteriorate the print quality and the lifetime of the head and
platen. When they adhere, clean the head according to the following procedures:
1. Take measures against static electricity such as a disposable wrist strap for the work.
2. Cleaning should be done with the presenter or the cutter (depends on your configuration) lifted up and
the platen part separated from the head (use the head-up lever).
Note: do not hit the thermal head surface with anything hard!
3. Wipe off the heating element part of the head surface lightly with cotton swabs to which Ethyl-alcohol
is applied. Be sure to clean the platen roll as well.
4. After Ethyl-alcohol has completely been dried, set the platen and perform the action check (print a self
test ticket and check the printing quality).
Note: do not use anything that may destroy the heating element, such as sandpaper. Do not apply
any unnecessary force to the thermal head.
Tests revealed that this procedure becomes necessary more often as the printer head gets used.
