    • An image forming apparatus supervising system includes a central control apparatus, a plurality of image forming apparatuses each having a memory and connected to the central control apparatus with a communication line, and a data communication apparatus connected to the plurality of image forming apparatuses and the central control apparatus using a communication line. An information code data transmitting device transmits information code data, having a plurality of levels in which character data is respectively included from the central control apparatus to the image forming apparatus, and a data reading device reads data corresponding to the information code data from the memory. A response data transmitting device transmits the data read from the memory to the central control apparatus via the data communication apparatus and the communication line. The central control apparatus changes all character data included in one or more levels lower than a prescribed level of the information code data with particular character data before transmitting the information code data when reading all data in the memory, which accords with character data included in one or more levels higher than the prescribed level of the information code data. Further, the data reading device reads only data of the memory which accords with the character data not changed with the particular character data when receiving the information code data.
    • 图像形成装置监视系统包括中央控制装置,多个图像形成装置,每个图像形成装置具有存储器并且连接到具有通信线路的中央控制装置,以及数据通信装置,连接到多个图像形成装置和中央 使用通信线路的控制装置。 信息代码数据发送装置将从中央控制装置分别包含字符数据的多个级别的信息代码数据发送到图像形成装置,数据读取装置从存储器读取与信息代码数据对应的数据 。 响应数据发送装置经由数据通信装置和通信线路将从存储器读取的数据发送到中央控制装置。 当读取存储器中的所有数据时,在发送信息代码数据之前,中央控制装置改变包括在低于具有特定字符数据的信息代码数据的规定级别的一个或多个级别中的所有字符数据,这符合包括在一个中的字符数据 或更高的水平高于信息代码数据的规定级别。 此外,当接收到信息代码数据时,数据读取装置仅读取与特定字符数据未改变的字符数据一致的存储器的数据。
