Offices needing high-volume monochrome output

Suitable for businesses and individuals running compatible Unisys laser printers who want a lower-cost alternative to the original cartridge. Not for users who require MICR toner for cheque printing or those operating printers outside the listed Unisys model range. Colour printing is not supported by this black-only cartridge.

Consistent output over long print runs

The high-yield formulation maintains crisp black text and clear contrast across the full 15000-page rated life at standard coverage.

Manufacturing standards ensure reliable feeding and toner adhesion throughout the cartridge lifespan.
