Lexmark LEX78C10K0 Black Laser Toner Cartridge

Product Description

The LEXMARK LEX78C10K0 is a black laser toner cartridge built for use in select Lexmark color laser printers. It uses Unison toner technology, which delivers consistent image quality and stable output throughout the life of the cartridge without requiring shaking or manual intervention. The cartridge is part of Lexmark's Return Program, meaning it is designed for one-time use and must be returned to Lexmark after depletion for remanufacture or recycling. Installation is straightforward and intended for office and workgroup environments where reliable print output is a daily requirement.

This cartridge is compatible with the following Lexmark printer models: CS421dn, CS521dn, CS622de, CX421adn, CX622ade, CX622de, CX625ade, and CX625adhe. These are color laser printers typically deployed in small-to-medium business and professional office environments. The LEX78C10K0 is a standard-yield black cartridge suited for moderate-volume print workloads in these systems.
