Programmed into a ROM chip on the CRUM (Customer Replaceable Consumables Module) for a reproduction apparatus, and/or in special software loaded in the machine controller and activated by an (existing) CRUM insertion signal, are instructions to display on the machine's user-interface a "no warranty", "voids warranty" or the like display if an improper or unauthorized CRUM was inserted, where the machine is sold with a warranty which is voided by doing so. Prior art CRUM systems are known which prevent or inhibit use of unapproved, refilled, and/or gray market or black market replacement consumables units, such as those for photoreceptors and/or carrier, toner, or ink jet cartridges. This system would not. It would merely cause the machine interface to initially or continuously display a notice or warning when an unauthorized CRUM is inserted.
