Save and print even more with our remanufactured ink cartridges! This listing contains 2, 18C1523 (#23) black and 1, 18C1524 (#24) color ink cartridges. Compatible with the following X and Z Lexmark Series printers: X3530, X3550, X4530, X4550, Z1410 and Z1420. These professionally remanufactured cartridges are original 18C1523 (#23) and 18C1524 (#24) inkjet cartridges which have been through one cycle of service and have been recharged. Each cartridge has been thoroughly cleaned and inspected for any possible shell leakage, tested on the operation of all electrical circuitry, and run through an actual print test. Our remanufactured cartridges are also backed by a two-year warranty and guaranteed to meet or exceed the same quality standards as the original (OEM) brand. Please note, retail packaging may vary and these items will only work with printers purchased within the United States and Canada. Due to changes in printer programming, the ink levels for these cartridges might appear to be low or empty; they are indeed full and will print a full yield.
