Go to www.hp.com/go/anticounterfeit when you install an HP print cartridge and the control-panel message says the cartridge is non-HP. HP will help determine if the cartridge is genuine and take steps to resolve the problem.

Your print cartridge might not be a genuine HP print cartridge if you notice the following:

●
The supplies status page indicates that a non-HP supply is installed.
●
You are experiencing a high number of problems with the print cartridge.
●
The cartridge does not look like it usually does (for example, the packaging differs from HP packaging).
