PURPOSE:To previously prevent the generation of paper jamming to a serious degree caused by the paper jamming to a slight degree by carrying out control so that the generation situation of paper jamming to the slight degree is displayed when the number of times of generation of paper jamming to the slight degree is the limit number of times or above. CONSTITUTION:Paper jamming is detected by a proper number of detecting means 1 and 1. Further, the number of times of generation of paper jamming to a slight degree is memorized by a memory means. Further, the limit number of times of paper jamming to the slight degree is set by a setting means. The memorized number of times of the generation and the set limit number of times are compared by a comparison control means 3, and a display means 2 is controlled by the comparison control means 3 so that the generation situation of the paper jamming to the slight degree is displayed when the number of times of generation is over the limit number of times. Accordingly, the generation of the paper jamming to a serious degree caused by the paper jamming to the slight degree can be prevented beforehand. |
