Lexmark Return Program

Lexmark Return Program Imaging Units are patented devices that are sold at a special price subject to the restriction that the imaging unit may be used only once. Following the initial use, the customer agrees to return the imaging unit only to Lexmark for remanufacture and/or recycling. The Return Program imaging units are designed to stop working once they reach their respective rated life (as established by Lexmark). In addition, the imaging units are designed to automatically update the memory in the customer’s printer to protect against the introduction of counterfeit and/or unauthorized third-party imaging units. If the customer does not accept these terms, replacement imaging units sold without these terms are available through www.lexmark.com.
