Remanufactured cartridges, like this alternative to the Kyocera TK5290M, are a great way of saving money and keeping your quality of print high. Quality is maintained by using many original Kyocera 1T02TXBNL0 parts and refilling the completed unit with a top-quality compatible magenta toner powder.Sadly, when recycling empty Kyocera 1T02TXBNL0 toner cartridges, many parts cannot be reused. So our manufactures simply replace these Kyocera components with their own compatible parts to maintain the TK5290M cartridges integrity.
