Frequently Asked Questions

Does the wireless model use a different cartridge than the wired MS421dn?

No. The "W" in MS421dw describes how the printer connects, not what it consumes — the toner cartridge is the identical 56F1000 rated at 6,000 pages. Connectivity hardware and the print engine are separate systems. So if you are moving between the wired and wireless versions of this printer, your cartridge stock carries straight over.

Our MS421dw sits in a corner with no supply cabinet nearby — how often will we change this?

Rarely, and that is the point of a 6,000-page rating on a printer like this. A home office or small team printing 300 to 500 pages a month gets roughly a year to eighteen months from one cartridge. When the low-toner notice finally appears, you have weeks of light printing left to arrange a replacement calmly.

Which other printers take this same cartridge?

A whole platform of them: MS321DN, MS421DN, MS421DW, MS521DN, MS621DN, MX321ADN, MX521ADE and MX521DE The listing is named for the MS421dw, but the 56F1000 is the shared cartridge for every model shown, wired and wireless alike. If a second office printer appears on that list, one spare on the shelf covers both machines.

What happens if the cartridge arrives damaged or prints poorly?

It is covered by a one-year warranty, and returns are free for a full year — send it back and we will replace or refund it, following the steps on our shipping and returns page. Our support team is reachable Monday through Friday, 9 AM to 5 PM CST. With warehouses in IL, PA, GA, and CA, most orders and replacements arrive quickly.

Is this a genuine Lexmark cartridge?

No — it is a new-build compatible cartridge made to the Lexmark 56F1000 specification, with the same 6,000-page rated yield and the same fit. It is not remanufactured and it is not an OEM product; we describe it as compatible on the listing because that is exactly what it is. Quality is backed by the same warranty we put on everything we sell.

How should I read the 6,000-page rating for our kind of printing?

The rating assumes standard 5% page coverage — a typical text page. A wireless printer serving a whole household or team often prints a mix: boarding passes and forms use little toner, while full-page graphics use much more. Most small offices land near the rating; treat it as a planning benchmark and you will not be far off.
