Lexmark MS823n toner
Your MS823n takes the 581U (high yield) and 581X (high yield). At our price that is about 0.6¢ a page.
The Lexmark MS823n is a mono laser printer in the MS823 series, which shares cartridges across 3 models.
It takes 2 cartridges: the 581U and 581X.
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.
