Genuine Lexmark black toner for CS521dn and CS622de

This genuine Lexmark 78C0UKG cartridge delivers black toner for the CS521dn and CS622de printers. It is built to match the engine specifications of those models. Offices that standardise on Lexmark hardware use it to keep print quality consistent across the fleet.

Thermal noise and power draw are not applicable

A toner cartridge has no moving parts, fans or electrical load of its own. It adds no audible noise and draws no power beyond what the printer already consumes. Normal printer operation remains unchanged after installation.

High-yield rating reduces replacement frequency

The 10500-page approximate yield means fewer cartridge changes during heavy print runs. That lowers the administrative overhead of ordering and storing spares. No bundled software or accessories are included with this supply item.

Questions about this item

How do I install the Lexmark 78C0UKG cartridge into my CS521dn, and what step do people often miss?

Open the front cover, pull out the old unit, shake the new cartridge gently side-to-side to distribute toner, remove the sealing tape completely, then slide it in until it clicks.

What part will need replacement after the 10500-page yield is reached?

The cartridge itself is the consumable; once the 10500-page yield is reached you replace the entire 78C0UKG unit.

What limit appears first during long print runs on the CS622de?

The 10500-page yield rating is the first limit you will hit; after that volume the toner is depleted and print quality drops.
