Chapter 4: Troubleshooting
Enter Hex Trace
mode
When unexpected characters print or characters are
missing, use Hex Trace to help you determine if there is
a problem with the language interpreter or the cable.
Hex Trace isolates printing problems by telling you
what information your printer is receiving.
To enter Hex Trace Mode:
1 Turn off the printer.
2 Open the top cover.
3 Turn the printer back on.
4 When the Error light comes on, indicating the
top cover is open, do a double button press.
5 When the Error light and Press Button light
blink, close the cover.
6 Do a double button press 3 times to scroll down
to Enter Hex Trace.
When the Enter Hex Trace setting is selected, the
operator panel Ready light is on solid, the Data
light is on solid, the Error light is blinking and the
Press Button light is blinking.
7 Do a long button press to start Hex Trace.
Data sent to the printer is printed out in
hexadecimal and character representation to help
isolate the source of the problem.
8 To exit Hex Trace, turn off the printer or press
the operator panel button to reset the printer.
