Removing Jammed Paper
Note: If the cutter remains blocked due to a paper jam, unplug the printer and use the manual lever to
move the cutter blade prior to perform the steps below.
If a paper jam occurs, follow the steps below:
• Cut the paper at the paper entrance.
• Unlock the presenter mechanism using the presenter lock.
• Unlock the head up switch raising the print head.
• Gently pull the paper out of the mechanism.
• Lock the head up switch back to initial position.
• Lock the presenter.
Key Panel
The key panel gives visual printer status and manual control to the operator.
These functions are accomplished using one switch and LEDs, described below:
• POWER LED: This green LED will be on whenever power is applied to the printer and the power switch is on.
• PAPER LED: This red LED will be on when the printer is without paper. If the print head is up, this red LED
will blink.
• ERROR LED: This red LED will blink in error conditions. See ERROR TABLE on page 25.
• PAPER FEED BUTTON: Use to feed paper line by line with fast button touches or feed paper continuously, by
pressing and holding down the button.
11
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.
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:
- 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 to wait the self-test. 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 two communication protocols: 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 a –12V voltage level.
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.

This section describes tests that are implemented in the kiosk printer microcode (firmware) as well as SWs that
may be run in order to help diagnosing issues.
Hexadecimal Dump Mode: This feature allows experienced users and programmers to see exactly what data is
being sent to the printer. It can be useful in finding software problems. When you turn on the hex dump mode,
the system prints all commands and other data in hexadecimal format along with a guide section to help you
find specific commands.
To use the hex dump mode, follow these steps:
1. Make sure that the printer is off.
2. Hold down the PAPER FEED button while you turn on the kiosk printer
3. Release the PAPER FEED button while the system prints a menu asking you to selecting the mode.
4. Press once more the PAPER FEED button.
5. Run any software program that sends data to the kiosk printer. The system prints the message “Data
Dump Mode” and then all the codes it receives in a three-column format. The first column contains the
bytes number, the second column contains the hexadecimal codes and the third column gives the ASCII
characters that correspond to the codes.
#
0000
0008
0016
6. Turn off the printer or reset it to turn of the hex dump mode.
• In the ASCII column a dot (.) is printed for each code that has no ASCII equivalent.
Self-Test: The self-test lets you know if your printer is operating properly, in stand-alone mode, with no communication.
This test may be run to help diagnosing problems that are not related to communication. (Ex.: mechanism, cutter,
etc).
To run a self-test, follow these steps:
1. Make sure that the printer is turned off.
2. While holding down the PAPER FEED button, turn on the printer.
3. When the printer starts printing, the PAPER FEED button can be released.
4. A message will be printed asking you waiting for the self-test. In the self-test you will find the
printer firmware version.
5. After printed the LEDS (led error and led paper) will blinking two times. To start a new self-test
press PAPER FEED button once.
Run-In: Run this test after a service procedure that includes parts replacement, specially in the presenter
module.
To run Run-In, follow these steps:
1. Make sure that the printer is off.
2. Hold down the PAPER FEED button while you turn on the kiosk printer
3. Set free the PAPER FEED button while the kiosk printer prints on the paper asking you to selecting
the mode.
4. Press twice more the PAPER FEED button.

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.
Lubrication:
Lubricate the presenter axle and bearings once a year, at least.
Clean axle and bearings, removing deposits of paper dust, aply the lubricant and remove any excess of oil.
Attention:
- Do not lubricate gears
- Use a high viscosity lubrificant. Low viscosity lubrificants are very likelly to be removed by force of axle
rotation
36
See details on the lubrication points in figures below.
Parts to be cleaned and lubricated:
