These pistol type refillable cartridges have been fitted withALL chips neccessary for operation and handling of larger amounts of ink. They have been tested in our 3880 to make sure that all the chips are working and communicating with the printer. No ink has been placed in these carts. Since a complete set of OEM chips needed to be installed, we wanted to make sure that everything worked with the ARC chips. No problems with our printer.
Most cartridges of this type do not come with the necessary ARC chips or the OEM chips neccessary for everything to work. They are usually sold as extra. Ours have been installed and tested. We will ship anywhere within the continental USA. Happy offerding
