Lexmark LEX78C00KG CS521DN GSA - Black Toner - 2,000 Page Yield

The Lexmark LEX78C00KG CS521DN GSA is a black laser toner cartridge with a stated yield of up to 2,000 pages, suited to users replacing black toner in a compatible Lexmark printer.

Recommended For

• Teams replacing black toner in a compatible Lexmark CS or CX printer, including the CS521dn; confirm the exact model before ordering.
• Small-office users whose routine printing is mostly black text and who prefer a standard-yield cartridge rated for up to 2,000 pages.
• Organizations buying through GSA channels that need the 78C00KG black Return Program cartridge for a listed compatible printer.

Real-World Use Scenarios

• When a compatible Lexmark printer runs low on black toner, replace the cartridge to resume printing black text and graphics; Lexmark’s guide describes removing the used cartridge and inserting the replacement.
• For routine office paperwork—such as reports, invoices, and forms—the black cartridge supplies the printer’s black output. Its rated yield is about 2,000 pages under specified test conditions; actual yield varies with print coverage and use.
• In a small office that prints black-and-white documents regularly, this standard-yield cartridge can serve as a replacement supply; users should plan replenishment around their print volume rather than treating 2,000 pages as a guaranteed count.
• For a color printer used mostly for documents with black text, replacing the black cartridge replenishes that toner supply without requiring a color cartridge replacement at the same time.
• For departments printing frequent or long black-document batches, the 2,000-page standard-yield cartridge may need replacement more often than a higher-yield option; compare the printer’s compatible cartridge choices before setting a restocking routine.
