Abstract
A method for detecting whether a cartridge installed in an imaging apparatus is potentially counterfeit includes determining whether a usage threshold has been reached by the cartridge; determining whether the cartridge was previously installed in the imaging apparatus; and determining that the cartridge is potentially counterfeit if the usage threshold has been reached and the cartridge was not previously installed in the imaging apparatus.
