Our remanufactured Hewlett Packard CF410X toner has been produced with closely inspected and cleaned components from the genuine cartridge. Anything that has not been reused is replaced with a compatible component designed to work in harmony with the rest of the HP 410X. The completed remanufactured Hewlett Packard CF410X cartridge is then filled with high quality black toner powder. This toner has been designed to fuse at the optimum temperature produced by your printer, to ensure as much powder as possible is fused from the HP 410X cartridge onto the paper for an estimated 6,500 pages.
