Running costs should always be a concern for colour laser printer owners, so if you need the lowest cost per page from your original Xerox toners, we would recommend this 006R04393. The 006R04393 is a high capacity Xerox magenta toner cartridge that offers an estimated 2,500 prints. The high number of pages it is capable of producing and the quality of Xerox consumables in general, mean the 006R04393 is sure to impress. Each Xerox 006R04393 comes fully guaranteed by the manufacturer themselves and is the best overall genuine consumable for the C230 and C235, as far as we are concerned.
