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 defect
on the print job indicates which particular part may be causing the defect.
Notes: Defects in graphics will be spaced very slightly further apart for the print cartridge and PC kit but the difference
will not be noticed between two adjacent defects.
Some components can be cleaned with a clear, dry, and lint-free cloth. Otherwise a new FRU will have to be used.
If the defect appears on the printed side of a single-sided print job, replace the toner cartridge before replacing the fuser.
For example, the distance between these two marks represents a
repeating defect that occurs every 29.0 mm (1.14 in.), which
means the charge roll may need to be replaced.
