Print defects guide
Match a set of repeating defects on a print job to the marks on one of the vertical lines. The line that best
matches the defects on the print job indicates which particular part may be causing the defect.
For example, the distance between these two marks represents
a repeating defect that occurs every 28.3 mm (1.11 in.), which
means the charge rollers may need to be replaced.
