These are original HP ink-jet cartridges which have been through one cycle of service and have been recharged. The HP ink cartridges arent just refilled; they undergo an extensive process that ensures quality prints. The empty cartridges are first visually & electronically tested to ensure the circuitry is intact; they are then completely disassembled and go through an ultrasonic cleaning. Then the HP 21 & 22 cartridges are filled with the same ink formulation as the originals, the internal back pressures are inspected for any possible shell leakage and they are once again tested for all electrical circuitry. Finally, they are run through an actual print test. If the C9351AN and C9352AN inkjet cartridges pass our rigid standards, they have been remanufactured for your HP printer! The black cartridge uses a formula of Pigment-based ink for archival print life and the color cartridge uses dye based inks for color stability. We offer a 100% Satisfaction Guarantee on our Remanufactured HP ink cartridges.
