The remanufactured Canon 731M cartridge is a high quality magenta recycled toner cartridge that has been produced using parts from the Canon original. As a result you can expect the same high page yield a genuine Canon 6270B002 laser toner cartridge when used with the Canon i-SENSYS MF-8280CW and all other compatible printers. The toner powder in this remanufactured Canon 731M toner cartridge has been specially formulated to fuse at the same temperature as an original laser toner cartridge to give comparable print quality. No additional drum unit is required as the 731 cartridge itself contains everything your printer needs to fuse the toner to paper.
