PROBLEM TO BE SOLVED: To display device abnormality occurrence information in the state of favorable availability.SOLUTION: An image formation device 1 generates, on the basis of information on the whole constitution thereof and arrangement positions of components, a block diagram showing the whole constitution of the image formation device 1 which clearly indicates the positions of the components. When an abnormal state of a component is obtained, the image formation device 1 extracts an abnormality-receiving component which receives an influence of the abnormal state from correlation between components in operation of the image formation device 1 and in which an abnormality occurs in operation and the device gives state display information indicating the abnormal state about an abnormal component and the abnormality-receiving component to the arrangement positions of the components on the block diagram to be displayed on a display unit.SELECTED DRAWING: Figure 1 |
