Electronic apparatus and image forming apparatus

摘要

One of two replaceable components is selectively detachably attached to an apparatus. A first component includes first information that includes first lifetime indicative of a lifetime of the first component and is used for managing usage of the first component. A second component includes second information for managing usage of the second component. A controller determines, based on one of the first and second lifetimes, whether the apparatus should operate. The controller drives the apparatus to operate based on the first lifetime if a read/write section successfully reads the first lifetime from one of the first and second components that has been attached to the apparatus. The controller drives the apparatus to operate based on the second lifetime if the read/write section fails to read the first lifetime from one of the first and second components that has been attached to the apparatus.

主权项

1. An electronic apparatus comprising:
a body; a replaceable component detachably attached to the body, and including a first memory that stores information about the replaceable component; a second memory that is disposed within the body and stores first lifetime information therein; a reading section configured to read the information about the replaceable component from the first memory; and a controller configured to manage a lifetime of the replaceable component, wherein if the information about the replaceable component that is successfully read by the reading section includes second lifetime information that designates a specified lifetime for the replaceable component, the controller manages the lifetime of the replaceable component in accordance with the second lifetime information, and wherein if the information about the replaceable part that is successfully read by the reading section does not include the second lifetime information, the controller manages the lifetime of the replaceable component in accordance with the first lifetime information.
