Compatible toner for Unisys UDS-640-N11

This two-pack of black toner cartridges replaces Unisys part 81-6404-999. It is built for offices and home users who print high volumes on these specific laser printers. The cartridges are new and designed for 110V machines sold in the U.S.

Extra high yield of 36000 pages at 5% coverage

The rated yield reduces the frequency of cartridge changes during large print runs. Manufacturing follows ISO 9001 and ISO 14001 standards using new and recycled components. Use of these compatibles does not void the printer manufacturer warranty under U.S. law.

Not for colour printing or non-Unisys machines

Buyers who need colour output or MICR toner cannot use this black-only cartridge. Printers outside the UDS-640-N11 and UDS-650-N11 series are not supported by this part number.

Questions about this item

When will the SuppliesMax 81-6404-999 cartridge need replacing?

Each cartridge yields up to 36000 pages at 5% coverage, so replacement timing depends on your monthly print volume.

What limits continuous printing with the SuppliesMax 81-6404-999?

The 36000-page yield at 5% coverage is the rated limit; heavier coverage or non-stop runs will reach that limit sooner.

How much heat or noise does the SuppliesMax 81-6404-999 add during all-day printing?

The cartridge itself adds no measurable heat or noise; those come from the Unisys UDS-640-N11 or UDS-650-N11 printer's fuser and fans.
