Reminder: Dynamic security enabled printer. This Firmware includes dynamic security measures, which are used to block cartridges using a non-HP chip or modified or non-HP electronic circuitry. The printer is intended to work only with new or reused cartridges that have a new or reused HP chip or circuitry. Periodic firmware updates will maintain the effectiveness of the dynamic security measures and block cartridges that previously worked. More at: www.hp.com/learn/ds.
