The Return Programme cartridges are licensed for single use only and are designed to stop working after the delivery of a fixed amount of toner. A variable amount of toner will remain in the cartridge when replacement is required. In addition, the cartridge is designed to automatically update the memory in your printer to protect against the introduction of counterfeit and/or unauthorised third-party cartridges.
