Lexmark MS621dn toner
Your MS621dn takes the 561U (high yield), 561X (high yield) and 561H (high yield). At our price that is about 0.9¢ a page.
The Lexmark MS621dn is a mono laser printer.
It takes 3 cartridges: the 561U, 561X and 561H.
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.
