Troubleshooting
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
on page 201.

persist or are
not covered in this section.

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.
