PURPOSE:To facilitate a jamming processing in a system printer, by displaying a unit which causes jamming and the unit in which a jammed sheet exists when the jamming is generated. CONSTITUTION:In a first display part 14A, jamming generation display 141 and jamming cause unit display 142 are provided, and in the jamming generation display 141, a jamming pattern shown in figure can be visualized by the illumination of a LED (light emitting diode) at the time of generating the jamming. The jamming cause unit display 142 is a one digit numeric display device by the LED of 7 segments, and displays the unit which causes the jamming in a numeric value. In a second display part 14B, the unit in which the jammed sheet exists, or a jamming unit display 143 on which eight LEDs representing a position are arranged are provided in a simulation drawing representing the constitution of a system. The numeric value attached on each LED in the jamming unit display 143 shows also the numeric value to be displayed on the jamming cause unit display 142. |
