PURPOSE:To easily pursue the cause of the occurrence of an abnormality in a remote area by storing the practical use information of an image forming device in a storage means, and reading out the practical information before and after the occurrence of the abnormality, and transmitting it to the outside when the abnormality occurs. CONSTITUTION:The information of various detecting switches 70 are repeatedly stored in a second memory 66 by every 1ms by a memory controlling part 67. When the abnormality such as paper jamming occurs in a copying machine main body 1, the memory controlling part 67 is informed of the abnormal information by a master controlling part 60, and also the storing action to the second memory 66 is stopped by the memory controlling part 67. And the requirement of a transmission from an external device 81 makes twenty-seconds information stored before and after the occurrence of the abnormality transmitted by the memory controlling part 67 through an interface 63 for transmitting. The external device 81 analyzes the abnormality by means of this received information. Thus, the cause of the occurrence of the abnormality can be easily pursued without going to a setting field. |
