Lexmark MS810dtn toner and drum
Your MS810dtn takes the 521 (standard yield), plus the 520Z drum. At our price that is about 0.8¢ a page.
The Lexmark MS810dtn is a mono laser printer in the MS810 series, which shares cartridges across 6 models.
The cartridge it takes is the 521, rated by Lexmark at about 6,000 pages, which works out to roughly 0.8¢ a page at our price of $48.99.
The drum is a separate part on this printer. The 520Z is rated for about 100,000 pages, so it outlasts several toner cartridges and only needs replacing when the printer reports drum life, not every time you change toner.
When you compare prices, compare cost per page rather than the sticker price: a cheaper cartridge with half the rated yield costs more to run. Every cartridge here ships free, is covered by our printer damage protection and can be returned within 90 days, opened or not.
