Dynamic security
Learn about dynamic-security-enabled printers.
Certain HP printers use cartridges that have security chips or electronic circuitry. Cartridges using a non-HP chip
or modied or non-HP circuitry* might not work. And, those that work today might not work in the future.
As is standard in the printing business, HP has a process for authenticating cartridges. HP continues to use
security measures to protect the quality of our customer experience, maintain the integrity of our printing
systems, and protect our intellectual property. These measures include authentication methods that change
periodically and might prevent some third-party supplies from working now or in the future. HP printers and
original HP cartridges deliver the best quality, security and reliability. When cartridges are cloned or
counterfeited, the customer is exposed to quality and potential security risks, compromising the printing
experience.
*Non-HP Chips and modied or non-HP electronic circuitry are not produced or validated by HP. HP cannot
guarantee that these chips or circuitry will work in your printer now or in the future. If you are using a non-
original HP cartridge, please check with your supplier to ensure your cartridge has an original HP security chip or
unmodied HP electronic circuitry.
