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.
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.
