What this cartridge is and who buys it

The Lexmark 78C00KG is a genuine black toner cartridge built for Lexmark laser printers. It uses Unison toner and a shake-free print system to deliver consistent image quality across a standard yield of 2000 pages. It is intended for owners of compatible Lexmark devices who want original supplies.

Who this suits and who should look elsewhere

This cartridge fits the CS421, CS521, CS622, CX421, CX522, CX622 and CX625 models. Buyers with different printer models or those who need colour toner should look elsewhere. It is not suitable for high-volume environments that would benefit from a higher page yield.

Capacity and headroom

The cartridge is rated for 2000 pages, making it suitable for low-volume printing where upfront cost matters. It will run out quickly in busy offices or shared workgroups that print larger daily volumes.

Questions about this item

Which Lexmark printer models accept the 78C00KG cartridge?

The 78C00KG works with Lexmark CS421, CS521, CS622, CX421, CX522, CX622 and CX625 laser printers.

Will the 2,000-page yield change if I keep an older drum unit in the printer?

Yield is rated at 2,000 pages for the toner itself; an older drum unit may affect print quality but not the toner page count.

How can I confirm the cartridge is printing correctly after installation?

Print a test page; the output should show consistently smooth black text and graphics with no shake-related defects.
