    • 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.
    • 两个可替换部件中的一个可选择性地可拆卸地附接到装置。 第一组件包括第一信息,其包括指示第一组件的寿命的第一生命周期,并且用于管理第一组件的使用。 第二组件包括用于管理第二组件的使用的第二信息。 控制器基于第一和第二寿命中的一个来确定设备是否应该操作。 如果读/写部分从已经附接到设备的第一和第二组件中的一个成功读取第一个寿命,则控制器基于第一个寿命来驱动设备操作。 如果读/写部分不能从已经附接到设备的第一和第二组件中的一个读取第一寿命,则控制器基于第二寿命来驱动设备操作。

    • An image forming apparatus includes a density detection part and a control part to correct a density of developer image. The control part causes the density detection part to detect a density of first developer image and second developer image to obtain a first density detection result, and to detect a second density detection result that is another density detection result, and afterwards computes a first density comparison value by comparing the first density detection result with the second density detection result and corrects the density of the first developer image by subtracting the first density comparison value from the first density detection result.
    • 图像形成装置包括密度检测部和用于校正显影剂图像的浓度的控制部。 控制部使密度检测部检测第一显影剂图像和第二显影剂图像的浓度,得到第一浓度检测结果,并检测作为另一浓度检测结果的第二浓度检测结果,之后计算第一浓度比较 通过将第一浓度检测结果与第二浓度检测结果进行比较,并且通过从第一浓度检测结果中减去第一浓度比较值来校正第一显影剂图像的浓度。

    • An image forming apparatus includes a main body and a replaceable component. The main body includes a first storage unit storing first authentication informations for authentication with the replaceable component, a data storage unit storing authentication data for choosing the first authentication information. The replaceable component includes a second storage unit storing second authentication informations corresponding to the first authentication information. Authentication data is set to be different among different image forming apparatuses. The main body attempts authentication with the replaceable component using the first authentication information chosen based on the authentication data. When the second authentication information corresponding to the chosen first authentication information is stored, a control unit establishes connection between communication units of the main body and the replaceable component.
    • 图像形成装置包括主体和可更换部件。 主体包括:第一存储单元,存储用于与可替换组件进行认证的第一认证信息;数据存储单元,存储用于选择第一认证信息的认证数据。 可替换组件包括存储对应于第一认证信息的第二认证信息的第二存储单元。 认证数据在不同的图像形成装置中被设定为不同。 使用基于认证数据选择的第一认证信息,主体尝试使用可替换组件的认证。 当存储与所选择的第一认证信息相对应的第二认证信息时,控制单元建立主体的通信单元和可更换部件之间的连接。

    • An image formation apparatus includes an image formation apparatus body, and a replacement member detachably provided in the image formation apparatus body and configured to be used for image formation. The replacement member includes a first storage to store a life determination value used in life determination of the replacement member. The image formation apparatus body includes a connection section configured to be connected to the first storage of the replacement member, and a controller configured to operate in: a first processing mode of accessing the first storage of the replacement member to acquire the life determination value and managing the life of the replacement member based on the acquired life determination value; and a second processing mode of managing the life of the replacement member such that the quality of image formation using the replacement member is not lower than that obtained through operation in the first processing mode.
    • 图像形成装置包括图像形成装置主体和可拆卸地设置在图像形成装置主体中并被配置为用于图像形成的替换部件。 替换构件包括用于存储在替换构件的寿命确定中使用的寿命确定值的第一存储器。 图像形成装置主体包括被配置为连接到替换构件的第一存储器的连接部分和被配置为在第一处理模式中访问替换构件的第一存储以获取生命确定值的控制器,以及 基于所获取的寿命判定值来管理所述更换部件的寿命; 以及管理更换部件的寿命的第二处理模式,使得使用替换部件的图像形成的质量不低于通过第一处理模式中的操作获得的图像质量。
