Printer Tests

A sequence of automatic tests is performed during printer power-up. If any faults are detected at that time,
a fault message will display.
Before placing the printer in its operating environment, run test patterns to ensure proper operation and
print quality. The printer has a number of tests which allow you to check for proper printer operation and
print quality.
You can invoke the various test patterns from the Tools > Print Tests menu. For more information, see
Tools section.

Troubleshooting Common Situations

Occasionally, situations occur that require some troubleshooting skill. Possible problem situations and
potential solutions are listed in this section. While not every conceivable situation is addressed here, you
may find some of these tips helpful. Contact a qualified service technician for problems that persist or are
not covered in this section.

Interfacing

The printer will not function properly with an incorrectly wired cable or the wrong interface cable installed. If
the cable is suspect, contact Printronix or your authorized service representative.
When the printer is first powered up, it will reset itself to the communication default parameters. The
parameters are listed in the following table:
The printer interface configuration settings may be entered from the control panel.

Hex Dump Mode

Hex dump mode allows you to place the printer into a diagnostic mode in which the printer outputs a
hexadecimal data stream on the label for examination. The purpose of hex dump mode is to see exactly
what data is received by the printer, in order to debug forms.
