High-Yield Black Toner for Samsung ProXpress

This compatible toner cartridge replaces the Samsung CLT-K503L and is built for the ProXpress C3010DW and C3060FW MFP printers. It ships new from LD Products and contains a single black unit with dye-based ink. The cartridge is rated for approximately 8000 pages under ISO IEC 24711 test conditions.

8000-Page Yield Decides Fit

The decisive figure is the 8000-page approximate yield, measured to the ISO IEC 24711 standard. If your monthly output regularly exceeds this capacity, you will replace the cartridge more often than the rating suggests. Shelf life spans 24 to 36 months, so the toner remains viable for extended storage.

Suits Cost-Conscious Offices.

This cartridge suits offices that want lower supply costs without voiding the printer warranty. It is not for users whose ProXpress units were purchased outside the United States or Canada, as the chip is programmed for North-American models only. Buyers needing colour output must buy separate cyan, magenta and yellow cartridges.
