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 page 200.
