Lexmark's Return Program cartridges offer an effortless way to recycle your used supplies. As patented print cartridges, they are sold at a discounted price in exchange for a promise to return them to Lexmark after a single use. Once a predetermined amount of toner/ink is delivered, the cartridge will stop working and a small amount of toner/ink will be left for convenient replacement. Additionally, the cartridge automatically updates your printer's memory to safeguard against fake or unauthorized third-party cartridges. Recycling is simple, smart, and free with Lexmark.
