Genuine Lexmark Black Toner

The Lexmark 78C0XKG is an original equipment manufacturer cartridge built for Lexmark CS421, CS521, CS622, CX421, CX522, CX622 and CX625 laser printers. It delivers professional black output with an approximate yield of 8500 pages. The cartridge installs easily and is supplied new under the return programme.

Best for High-Volume Mono Printing

This extra high-yield black cartridge suits offices that print large volumes of monochrome documents on compatible Lexmark devices. It is not for users who need colour toner, require a multi-pack, or operate printers outside the listed CS and CX series.

Yield Decides Suitability

The single specification that determines fit is the 8500-page approximate yield at standard coverage. Buyers should match this figure against their typical monthly print volume to decide if the extra high-yield capacity matches their workload.

Questions about this item

Will the 78C0XKG cartridge work in my older Lexmark CS421dn printer?

Yes, the 78C0XKG is listed as compatible with the Lexmark CS421dn and CX421adn series, so it will install and print normally in that device.

How can I verify the 78C0XKG is printing correctly after I install it?

Print a test page from the printer menu; the output should show solid black text and graphics without streaks or fading, confirming the cartridge is seated and functioning.

Does the 78C0XKG box contain only the toner cartridge or are other parts included?

The package includes the single black toner cartridge only; no drum unit, waste container or maintenance kit is supplied and must be purchased separately if required.
