Repeating defects
Print quality defect locator chart
The printer has an internal copy of the defect locator chart under the Help Menu.
From the home screen, navigate to:
> Help > Print Defects
Verify the proper image size by measuring any of the marks on the printed chart and comparing them to the
corresponding measurement in the chart.
Using the charts
Measure repeating horizontal lines from the reference lines at the top to determine what may have caused the
lines to form in that pattern. Be sure to use portrait orientation for the test file.
