We offers the best alternative to the OEM (genuine) Hewlett Packard Q6471A cyan laser toner cartridge for your Color LaserJet 3600 printer series. Our Q6471A cartridges are refurbished to perfection for crisp, clear prints, every time. Each of these laser toner cartridges contains not only up to 85% new internal parts (such as OPC drums, wiper blades, and other parts), but also a new electronic 'smart chip' that allows your HP printer and our compatible Q6471A cartridge to interact and track toner usage. Without this chip your printer's toner level software will always think the cartridge is low. Laser toner you can rely on at a price you can afford.
