What items are returnable? All items can be returned within 30 days of receipt of your shipment in original condition. “Consumable” items like dampers, filters, tubings, wipers, cappers if used or with ink cannot be returned. You accept responsibility for proper installation. If you are not sure how to install the print head or any other spare, contact a trained repair technician to do the installation. Printheads are tested by the manufacturer and are not given a warranty. For more information regarding this point, call us at +1-800-616-0584. This is an industry standard that applies to printheads only.
