Go to www.hp.com/go/anticounterfeit when you install an HP toner 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 toner cartridge might not be a genuine HP toner 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 toner cartridge.
● The cartridge does not look like it usually does (for example, the packaging differs from
HP packaging).
