Troubleshooting Communication Problems
Use Dump mode to verify that the printer is receivi ng data from the
host correctly.
Using the Line Analyzer in Fingerprint
In Dump mode, the printer runs a Fingerprint progra m called Line
Analyzer. The Line Analyzer captures incoming chara cters on the
communication ports and prints them on one or more labels.
The easiest way to enter Dump mode is through Test mode or
Extended Test mode. For help, see
“Understanding Test Mode” on
page 21
.
After the printer enters Dump mode, it tells you it has entered Dump
mode by printing it on a label. The display shows t he Dump mode
icon and printer is ready to receive data.
While the printer is receiving data, the Ready-to-Work indicator
blinks. After a half of a second, if no more charac ters have been
received, the printer times out. The program considers the
transmission terminated and prints out a label.
The test pages do not
print.
tMake sure that the blue light is not blinking. If
it is, make sure your printer has media and that
the media cover is closed.
tMake sure that you can advance media by
pressing the Feed button.
Print quality is poor.
tClean the printhead. For help, see “Cleaning
the Printer” on page 48
.
tCheck the battery and recharge or replace as
necessary. For help, see
“Charging the
Batteries” on page 9
.
tCheck the quality of the media. Use only
Intermec media to ensure superior print quality
and product performance.
tCheck that the printer is set to the appropritae
Constant/Factory or sensitivity number for the
