HP printers are designed to work with original HP ink and toner cartridges. As is standard
in the printing business, HP printers use a process to authenticate cartridges. In certain HP
printers, this authentication process includes measures referred to as dynamic security. It
relies on the printer’s ability to communicate with the security chips or electronic circuitry on
the cartridges. HP uses dynamic security to protect the quality of our customer experience,
maintain the integrity of our printing systems, and protect our intellectual property.
In these dynamic security equipped printers, cartridges using a non-HP chip or modified
or non-HP circuitry* may not function. Further, since the dynamic security authentication
process can change during the life of the printer (including in response to firmware updates),
cartridges using a non-HP chip or modified or non-HP circuitry may function for a period of
time, but then cease to function. Non-HP cartridges that reuse an original HP security chip or
have unmodified HP electronic circuitry are unaffected by dynamic security.
