The Lexmark laser print cartridges are specifically designed to assure optimal print quality, with crisp, dark output. This print cartridge comes with oiled fuser wipers for customers that do extensive label printing. The Lexmark Optra T print cartridges are designed to work with Optra T printers (T610, T612, T614 and T616) and will not work with other products. Yield: 25,000 pages at approximately 5% print coverage at comparable industry settings (toner darkness = 5). Prebate supplies are now called Lexmark Return Program cartridges. Details of the license program remain the same. Only the name has changed. For a period of time, when you order a Return Program cartridge, you may receive a Prebate cartridge. We appreciate your patience during this transition. Lexmark Return Program Cartridges are sold at a discount versus the prices of regular cartridges in exchange for the customer's agreement to use the cartridge only once and return it only to Lexmark for remanufacturing or recycling. Regular cartridges without this license/agreement sold at regular prices are also available. Regular cartridges are also recyclable at no cost through Lexmark Cartridge Collection Program.Compatible Printers: Lexmark Optra T 710 Series, Lexmark Optra T 717, Lexmark Optra T 610 SX, Lexmark T 612 N SOL, Lexmark T 612 N, Lexmark 4069, Lexmark T 616 N SOL, Unisys UDS 25, Lexmark Optraimage T 610 SX, Lexmark T 612 SX, Lexmark T 610 Series, Lexmark T 717 N SOL, Lexmark T 614 DX, Lexmark T 612 V, Unisys UDS 20, Lexmark Optra T 610 N, Lexmark T 610 SX, Lexmark Optraimage T 614 DX, Unisys UDS 35, Unisys UDS 15, Lexmark Optra T 614, Lexmark T 612, Lexmark T 614, Lexmark Optra T 616 N SOL, Lexmark Optraimage T 610 Series, Lexmark Optra T 717 N SOL, Lexmark T 717, Lexmark T 610 N SOL, Lexmark Optra T 717 N, Lexmark Optra T 610 Series, Lexmark T 610 N, Lexmark Optra T 612 N SOL, Lexmark Optra T 614 DX, Lexmark Optra T 614 N, Lexmark Optra T 610, Lexmark Optra T 612 V, Lexmark Optra T 614 N SOL, Lexmark T 616, Lexmark Optra T 612, Lexmark T 717 N, Lexmark T 614 NL, Lexmark T 610, Lexmark T 614 N, Lexmark T 710 Series, Lexmark Optra T 616 N, Lexmark T 616 N, Lexmark Optra T 614 NL, Lexmark Optra T 612 N, Lexmark Optra T 612 SX, Lexmark Optra T 614 S, Lexmark T 614 S, Lexmark T 614 N SOL, Lexmark Optra T 610 N SOL, Lexmark Optra T 616
