    摘要： A method of diagnosing the operating conditions of an image processor comprising the steps of preparing a first pattern of data, a second pattern corresponding to the first pattern when it has been compressed normally, a third pattern of data, and a fourth pattern corresponding to the third pattern when it has been expanded normally; diagnosing an operating condition of the compressor by comparing data after the first pattern has been compressed by the compressor with the second pattern; and diagnosing an operating condition of the expander by comparing data obtained after the third pattern has been expanded by the expander with the fourth pattern. The independent diagnosis of the compressor and the expander allows the specific defective chip of component to be identified, thereby facilitating proper repair.

    摘要： An image processing system including a reconfiguration circuit, typically responding to fault detection. The image processing includes a data compressing unit for compressing image data generated by an image input terminal, a data storage unit for storing output compressed image data, a data decompressing unit for decompressing compressed data and for transferring the decompressed data to an output terminal. A control unit controls the system to compress and store image data, and then to repeatedly read out and transfer the stored data to the image output terminal. When a self diagnosis detects a fault in any one of the compressing unit, data storage unit, or data decompressing unit, the faulty unit is bypassed with a special data bus, thereby allowing system operating to continue.

    摘要： An image-forming system includes a determining section that, for each type of malfunction in image-forming apparatuses, determines a reference number of occurrences of the type of malfunction based on at least one of (1) a distribution of the number of apparatuses in which the type of malfunction has occurred against the number of occurrences of the type of malfunction and (2) a distribution of the number of apparatuses on which maintenance has been carried out against the number of occurrences of the type of malfunction; an extracting section that extracts a subgroup of apparatuses in which the malfunction has occurred a number of times larger than or equal to the reference number of occurrences; and a setting section that sets a criterion for maintenance based on a time series tendency of occurrence of the malfunction in an apparatus on which maintenance has been carried out in the subgroup.
