PROBLEM TO BE SOLVED: To satisfactorily investigate the cause of the generation of the error of a picture forming device. SOLUTION: The operational condition of a picture printing means 73 or the like is repeatedly stored as condition data in a non-volatile storing means 76 until an error is generated, and when the detection of the generation of the error is released, the condition data stored in the condition storing means 76 are printed and outputted from a picture printing means 73 or the like. The condition data printed and outputted in this ways indicate the operational condition just before the error is generated so that the cause of the generation of the error is satisfactorily investigated based on this. |
