The printer is designed to work only with ink cartridges that use newer or reusable HP chips, with dynamic security measures that prevent cartridges from using non-HP chips. Regular firmware updates ensure the effectiveness of the above measures and block previously used cartridges. Reused HP wafers allow ink cartridges to be reused, remanufactured, and refilled.
