56F1000 Black Toner Cartridge

When a printer runs out of black toner mid-task, replacing it should be straightforward—not a guessing game. This two-pack is made for compatible Lexmark laser printers and uses the 56F1000 cartridge number.

Each cartridge is rated for up to 6,000 pages at 5% coverage. That gives you a stated yield to weigh against how much you print.

You’ll appreciate it if you want two remanufactured cartridges for routine black-and-white printing. If you prioritize a remanufactured replacement, this fits that approach, if you prefer a new cartridge, this is not that product.

Where it shines

The practical appeal is having a spare ready when the first cartridge runs low. For a home office or small workgroup printing forms, drafts, and everyday documents, a two-pack can reduce the chance of an immediate second purchase. Picture printing a stack of invoices in the morning and keeping the other cartridge on hand for the next run.

The listing names compatible Lexmark models including the MS321dn, MS421dn, MS521dn, MS621dn, MX321adn, MX421ade, MX521de, and MX622ade, among others. Compatibility is the key decision here: match the printer’s exact model and the cartridge number before ordering, rather than relying on a similar-looking printer name. It is described as a remanufactured replacement, not a new original cartridge.

Highlights

The package contains two black toner cartridges, each identified as 56F1000 and 56F1H00 replacement toner. The listed yield is up to 6,000 pages per cartridge, measured at 5% coverage on Letter/A4 pages. Treat that as a reference point, not a promise for every job: pages with heavy black coverage can use toner faster than lightly printed documents.

Because the cartridges are remanufactured, this pack suits shoppers who are open to a replacement cartridge rather than specifically seeking a new one. The listing does not provide details about the remanufacturing process, included instructions, or a warranty, so those points cannot be weighed from the available product information. Check the model list carefully, especially if your printer name includes a suffix such as “dn,” “de,” or “adn.”

Best use cases

This pack makes most sense for regular black-and-white printing when your printer is one of the listed models and having a second cartridge available is useful. It may also suit someone stocking a shared office printer, where a spare can keep routine document work moving.

It’s not for you if your printer is not listed, you need color toner, or you only want a new original cartridge. A higher-volume or more demanding print setup may also call for comparing the stated yield and cartridge type with other options before settling on this pack. On the spec sheet, the yield depends on 5% coverage, so consider the kind of pages you actually print.

Final verdict

This 56F1000 two-pack is worth considering when the exact printer model is listed and you want two remanufactured black cartridges with a stated yield of up to 6,000 pages each. The useful tradeoff is clear: it offers a spare in the same purchase, but the listing gives limited detail beyond compatibility, pack size, and yield. Choose it for compatible, everyday document printing, skip it if you need color, an unlisted printer match, or a new original cartridge.
