Phaser 6130 Color Laser Printer Service Manual 5-21
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.
