Lexmark Unison Original Laser Toner Cartridge Black Pack

The Lexmark Unison Original Black Laser Toner Cartridge is a genuine replacement cartridge for Lexmark CX930, CX931, CX930dse, CX931dse, and CX931dtse printers, suited to users of these models who need black toner.

Recommended For

• CX930/CX931 office teams that print large volumes of black-and-white documents and want a high-capacity replacement; Lexmark lists a 28,000-page black cartridge for these printers.
• Organizations already using a Lexmark CX930 or CX931 who need a genuine black toner cartridge listed for their printer model.
• Workgroups that rely on consistent black text and grayscale output and prefer Lexmark’s Unison toner system, which the manufacturer positions for image quality and print-system reliability.

Real-World Use Scenarios

• When a compatible CX930 or CX931 runs low on black toner, replace it with the matching genuine Lexmark cartridge to resume black printing on that device.
• In a large workgroup, staff printing text-heavy reports, forms, or correspondence can use the black cartridge for monochrome jobs while the CX930/CX931 remains available for color work.
• For routine black-document printing on a shared office MFP, using the genuine cartridge made for the CX930/CX931 helps keep the supply matched to the printer rather than relying on an unsupported cartridge.
• When an office replaces used toner during supply maintenance, it can return the empty genuine cartridge through Lexmark’s Cartridge Collection Program where available.
