ABSTRACT:
A method for controlling an automatic discharge of a paper jammed in a copy machine, capable of eliminating a requirement for a user to directly remove the jammed paper. The method provides provides three jam removal modes, that is, an automatic jam removal mode for performing automatic try for removal of jam, a semi-automatic jam removal mode for performing a try for removal of jam when the user presses down the copying start key, and a manual jam removal mode for stopping the copy machine upon generation of jam, as in existing copy machines, thereby preventing deterioration of driving parts of the copy machine such as abrasion of rollers caused by forced discharge of the jammed paper, enabling the user to directly remove without opening a door of the copy machine while minimizing contamination of development and fixture parts of the copy machine and damage of driving parts of the copy machine, and capable of displaying signs indicative of a jam removing state and a manual removal of jammed papers, thereby enabling the user to recognize the state of the copy machine, and thereby obtaining a convenience in use.
