Our remanufactured Hewlett Packard CF400X toner cartridges retain the same 2,800 page estimated yield as the genuine article, but are offered at a reduced price. This low price is achieved by reusing many of the components within the original HP 201X and replacing whatever cannot be recycled with a quality compatible alternative. Assured that the remanufactured Hewlett Packard CF400X will perform as the original did mechanically, our trusted refurbishers then fill the cartridge with a high quality compatible black toner powder. The resulting cartridge lasts as long as the original HP 201X, gives comparable quality and is even compatible with all of the same laser printers.
