Lexmark has engineered its Optra T print cartridges as an integral component of the Optra T family of laser printers. They are designed and manufactured to meet the extraordinary demands of the Optra T laser printers with a superior yield of 10, 000 pages.
Return/Prebate cartridges are sold at a discounted price vs. the price of regular cartridges in exchange for the customer's agreement to use the cartridge only once and return the cartridge to Lexmark for recycling once it's empty. All toner boxes ship with prepaid postage labels for customers to return their empty cartridges for recycling.
