Compatible Extra High Yield Cartridge

This SuppliesMAX cartridge replaces the Unisys 81-6404-999 toner for UDS-640-N11 and UDS-650-N11 laser printers. It is a new aftermarket unit built to OEM specifications in ISO 9001 and ISO 14001 certified facilities. The single black cartridge is designed for 110V machines sold in the U.S. and carries a 30-day manufacturer warranty.

36000 Pages at 5% Coverage

The extra high yield rating delivers approximately 36000 pages measured at .05 coverage, suited for consistent high-volume office printing. Crisp black output and clear contrast are maintained across the cartridge life. Heavy graphics or dense text will reduce the practical page count below the rated figure. Buyers who need color output or MICR encoding should look elsewhere.

Unisys UDS-640-N11 and UDS-650-N11 Fit

This part number 81-6404-999 fits only the Unisys UDS-640-N11 and UDS-650-N11 series printers listed in the compatibility data. It will not work in other Unisys models or printers from different brands without a matching part number. Verify the exact machine model before purchase to avoid ordering the wrong cartridge.
