What does the error message '10.30.0X Unauthorized Cartridge' mean and how do I fix it?

This error means the administrator has configured the printer to use only genuine HP supplies, and a non-genuine or unauthorized cartridge has been installed. To resolve it, replace the cartridge with a genuine HP toner cartridge. If you believe your cartridge is genuine, visit www.hp.com/go/anticounterfeit to verify it. (Page 31)
