Discount Xerox Inkjet Cartridges - Our remanufactured Xerox inkjet cartridges are remanufactured in a modern facility. We only use virgin (one-time use) cores for remanufacturing. All of the Xerox inkjet cartridges we sell are quality tested at the time they are remanufactured. They are then filled with pigmented black ink to give you deeper, darker blacks and "wow factor" colors, even when printing on just ordinary copy paper.
