This defect typically occurs when the print cartridge has far exceeded its rated life of 18,000
pages. For example, if you are printing a very large quantity of pages with very little toner
coverage, toner might still remain in the print cartridge but you have printed more than
18,000 pages.

1. Replace the print cartridge.

2. Reduce the number of pages that you print with very low toner coverage.
