Lexmark LEX78C0XKG CS521DN GSA - Black Toner - 8,500 Page Yield

The Lexmark LEX78C0XKG is a black toner cartridge with an 8,500-page yield, suited to offices and other users who print black documents frequently on compatible Lexmark printers.

Recommended For

• Offices printing frequent black-and-white documents on a compatible Lexmark CS521dn that want a higher-yield replacement cartridge; Lexmark rates this cartridge for up to 8,500 standard pages.
• Shared workgroups using a compatible Lexmark printer that want fewer black-toner replacement cycles than with a standard-yield cartridge.
• U.S. government buyers sourcing a GSA-listed black toner cartridge for a compatible Lexmark printer and able to follow the Return Program terms.
• Organizations with a toner collection or recycling process that can return the used cartridge to Lexmark under the Return Program.

Real-World Use Scenarios

• When an office regularly prints text-heavy documents such as reports, letters, and internal records on a compatible Lexmark printer, this black cartridge supplies the toner for routine monochrome jobs; its rated yield is up to 8,500 pages, with actual yield varying by print coverage and use.
• For a shared CS521dn in a small or medium workgroup, replacing the black cartridge with this compatible 8,500-page-yield option can support recurring black-and-white office printing while reducing how often black toner needs replenishing compared with a lower-yield cartridge.
• When printing invoices, forms, or other business paperwork that is primarily black text, this cartridge provides the black toner; color pages still require the printer’s separate color toners.
• For a government buyer restocking a compatible CS521dn, the GSA listing identifies this part number as an 8,500-yield black extra-high-yield return-program cartridge, helping match the replacement supply to the printer and procurement listing.
