Lexmark return print cartridges The Lexmark return program for print cartridges gives customers patented print cartridges or print cartridges at a special price, if the purchaser agrees to use the cartridge or cassette purchased only once and to return it to Lexmark for remanufacturing or recycling. The patented cartridges or cassettes are licensed for one-time use only and cannot be used again after a certain amount of ink and/or toner has been dispensed. A varying amount of ink and/or toner may remain in the cartridge or cassette when it needs to be replaced. Replacement cartridges or cassettes are available but are not sold under these terms.
