DYNAMIC SECURITY ENABLED PRINTER – Certain HP printers are intended to work only with cartridges that have a new or reused chip or electronic circuitry. These printers use dynamic security measures to block cartridges that have a non-HP chip or modified or non-HP electronic circuits. Periodic firmware updates will maintain the effectiveness of these measures and block cartridges that previously worked. Reused HP chips and electronic circuits enable the use of reused, remanufactured and refilled cartridges.
