Lexmark Unison Original Toner Cartridge Black 55B1X0E

The Lexmark 55B1X0E is an original black, extra-high-yield toner cartridge rated for up to 20,000 pages, suited to offices with compatible Lexmark laser printers that print frequently.

Recommended For

• Workgroups with frequent black-and-white document jobs that want an extra-high-yield cartridge and fewer toner replacements.
• Organizations with a contract-managed Lexmark MS431 printer that need its specified 55B1X0E Corporate Return Program cartridge.
• Offices printing mostly text and monochrome business documents that want Lexmark’s original Unison toner for consistent black output.

Real-World Use Scenarios

• In a contract-managed Lexmark setup that supports 55B1X0E, an office replacing an empty black toner cartridge can return to routine monochrome document printing; confirm the printer’s cartridge compatibility before ordering.
• For a workgroup printing recurring business paperwork, such as forms, invoices, and internal documents, the extra-high-yield cartridge can reduce how often toner needs replacing; actual page count varies with print coverage and usage.
• When an office has a large batch of black-and-white pages to print, this cartridge is intended for extended runs between toner changes, helping keep the printer available for everyday document jobs.
• For routine two-sided office printing, the cartridge supplies black toner for documents while a compatible Lexmark printer handles duplex printing; this can help teams use less paper on suitable jobs.
• A small workgroup with steady document-printing needs can keep an extra cartridge on hand to simplify replenishment, but should check that its printer and contract arrangement support the 55B1X0E cartridge.
