Print cartridge authentication


The printer automatically authenticates the print cartridges when the cartridges are inserted into the printer. During authentication, the printer will let you know whether a cartridge is a genuine HP print cartridge.

If the printer control panel message states that this is not a genuine HP print cartridge and you believe you purchased an HP print cartridge, see HP fraud hotline.
