Genuine Lexmark Black Toner

The Lexmark LEX78C00KG is a genuine black toner cartridge built for Lexmark laser printers. It serves offices and home users who need reliable monochrome output without third-party variability. The cartridge integrates with Lexmark Rewards so eligible pages earn free supplies over time.

Shake-Free Print System

A shake-free print system removes the need to agitate the cartridge before installation, reducing handling mess and saving time during swaps. The compact design fits the printer bay without forcing adjacent components. Installation follows a straight insert-and-click motion that most users complete in under a minute.

High-Yield 2000-Page Replacement

This high-yield cartridge replaces standard-capacity black toners that run out after fewer pages, cutting the frequency of interventions in busy periods. The jump is worth it when print volumes regularly exceed the lower-yield threshold and downtime for changes disrupts workflow. Buyers who need colour output or higher page counts per cartridge should look at separate colour or extra-high-yield lines.
