ABSTRACT:
The present invention provides an image processing apparatus which can promptly detect whether or not a jam has been removed in the case of occurrence of the jam such as a paper jam. A paper feeding apparatus1bincludes a paper feed tray11, a pickup roller61, a paper roller63, a sorting roller64, feeding rollers66a, resist rollers67, a paper ejection roller73, a passage detection sensor69, an overlapped feeding detection sensor68and a second detection apparatus71. An image processing apparatus100includes a position detection portion41for detecting a location of a jam which occurs during feeding of recording paper, a determination portion42for determining a jam state based on a detection result of the position detection sensor69, an examination portion43for examining whether the jam has been resolved and a resuming portion44for resuming the processing when an examination of the jam location by the examination portion43is finished. If the position detection sensor69detects the occurrence of the jam (S2), the determination portion determines the jam state and simultaneously provides notification of the occurrence of the jam (S4). If clearing work is finished (S5), the examination portion43feeds a test sheet (S6). It is detected whether or not the test sheet passes through the jam location (S8), and the processing is resumed if it is detected within predetermined time (S10).
