Print-Quality Troubleshooting
Repeating Defect Measurement
Horizontal lines and/or spots that occur
periodically are usually caused by one of
the printer’s many rollers. However, the
interval does not necessarily match the
circumference of the roller. Compare the
print defect intervals on the test print with
the gauges on the Pitch Chart that can be
printed from the diagnostics in Service
Mode. The problem may be solved easily
by the check.
To print the Pitch Chart, print the
Contamination Check test prints: Service
Mode > Test Print > Contamination
Check.
