HP 60, 61, 62, 63, 64, & 65 Ink Cartridges: Ensure the ‘Cartridge Protection’ feature is turned OFF or DISABLED on your HP printer. If your HP printer is displaying the error message ‘ protected cartridge‘ or ‘ the indicated cartridge can only be used in the printer that initially used it and must be replaced’ then the ink cartridge has been permanently disabled for use in all printers, except for the original printer that it was first installed into.*
