Image forming apparatus

#1. Field of the Invention

#The present invention relates to an image forming apparatus for forming an image on a sheet by conveying the sheet, and more particularly, to an image forming apparatus in which, when a sheet in an abnormal state is discharged, the user can discriminate that sheet from normal sheets.

#2. Description of the Related Art

#FIG. 1 is a cross-sectional view illustrating a copier, serving as an image forming apparatus, in which the copier is cut along a sheet conveying direction, according to an embodiment of the present invention;

#FIG. 2 is a block diagram illustrating control of the copier shown in FIG. 1;

#FIG. 3 is a diagram illustrating an external appearance of an operation panel;

#A description will now be provided of a copier, serving as an image forming apparatus, according to a preferred embodiment of the present invention with reference to the drawings. Image forming apparatuses include copiers, facsimile apparatuses, printers, composite apparatuses in which these apparatuses are combined, and the like. The present invention is applied not only to copiers, but also to facsimile apparatuses, printers, composite apparatuses and the like.

#(Explanation of the Configuration and the Operation of the Copier)

#FIG. 1 illustrates the entire configuration of a copier 100 according to the embodiment, and is a cross-sectional view obtained by cutting the copier along the sheet conveying direction. The copier 100 includes an original-feeding device 1000, an image reader 200, a printer 300, a finisher 500, and the like. The original-feeding device 1000 sequentially conveys sheets of an original set by the user starting from the leading page from the left to the right, in the state shown in FIG. 1, on platen glass 102 after causing the sheets to pass through a curved path, and thereafter discharges the sheets onto a discharged-sheet tray 112. At that time, a scanner unit 104 remains to stop by being held at a predetermined position.
