Genuine Lexmark yellow toner

The Lexmark 78C0X40 is a genuine yellow toner cartridge rated for 5000 pages. It uses Lexmark Unison toner formulation for consistent image quality and shake-free operation. The cartridge is supplied new and participates in the Lexmark Cartridge Collection Programme for free recycling.

Best for high-volume colour printing

Offices running Lexmark CS421dn, CX522ade or CX421adn printers will benefit from the extra high yield and lower cost per page. Buyers who need a different colour, a standard yield cartridge or a toner for non-Lexmark devices should look elsewhere.

Drop-in cartridge for compatible Lexmark printers

Installation requires no additional hardware or tools beyond the supported printer models listed. The high-yield capacity reduces replacement frequency, freeing up storage space and admin time for supply management. The return programme simplifies end-of-life disposal.
