Warning—Potential Damage: Supplies and parts without Return Program agreement terms may be reset and remanufactured. However, the manufacturer’s warranty does not cover any damage caused by non-genuine supplies or parts. Resetting counters on the supply or part without proper remanufacturing can cause damage to your printer. After resetting the supply or part counter, your printer may display an error indicating the presence of the reset item.
Remove any non-Lexmark supply from your printer to avoid damage. Installing non‑Lexmark supplies may void the printer warranty.
Keep your printer performance at top level. Use only Lexmark branded parts and supplies.
