This defect typically occurs when the toner cartridge has far
exceeded its rated usage of 10,000 pages (for example, printing a
very large quantity of pages with very little toner coverage).
1 Replace the toner cartridge.
2 Reduce the number of pages that you print with very low toner
coverage.
3 Use the 6,000-page cartridge if you cannot reduce the number of
pages with very little toner coverage (part number C8061A).

being met (see General specifications on page 202).
