Abstract
In a server authentication process, a controller (a) transmits identification information of a consumable unit to an authentication server, and causes the authentication server to determine whether the consumable unit is a genuine product or not on the basis of the identification information and (b) receives the genuine product determination result from the authentication server. Further, (a) upon detecting replacement of the consumable unit, the controller reads identification information from a storage device of the consumable unit, performs the server authentication process based on the read identification information, and stores the received genuine product determination result into the non-volatile storage device, and (b) when powered on, the controller determines whether the consumable unit currently mounted is a genuine product or not on the basis of the genuine product determination result stored in the non-volatile storage device, without performing the server authentication process.
