The Sharp FO-4470 Laser Toner from LD Products is a professionally remanufactured laser toner that is guaranteed to meet or exceed the print quality of the OEM FO-4470 Sharp toner. We also carry the remanufactured FO-47DR drum unit for the Sharp FO-4470. You can replace the FO-50ND laser toner without replacing the FO-47DR drum unit. You will need to replace the FO-47DR drum unit occasionally. Purchasing our Sharp FO-4470 laser toner is an excellent way to save money without sacrificing quality. Our Sharp FO-4470 Laser Toner Cartridge has a 'Two Year 100% Quality Satisfaction Guarantee'. The use of our compatible laser toner and drum for the FO-4470 Sharp toner does not void your printer's warranty.
