This Samsung MLT-D305L Remanufactured toner cartridge is a replacement laser cartridge that can be used instead of buying new OEM (original brand) Samsung toner cartridges. This product is manufactured to be comparative to the original in terms of quality and page yield. Our stringent quality standards for remanufacturing ensure that all worn out parts are 100% replaced and that the cartridge is refilled with brand new high quality premium toner. This results in a remanufactured Samsung MLT-D305L toner cartridge with new aftermarket components, ultra-fine particle toner and an exclusive sealing process to ensure a leak-proof cartridge. Extensive testing and R&D have enabled us to produce cartridges that will not only save you money, but also provide a high quality product to ensure long term customer satisfaction.
