a copy paper counting method for a copying apparatus including the steps of : counting the copy paper by means of a first counter ; terminating the feed of the copy paper when the counting value stored in the first counter becomes equal to the preset number of the copy paper ; counting the discharged copy paper by means of a second counter ; and detecting paper jamming , and supplying the counting value of the second counter to the counting value of the first counter . it is not necessary to preset the number of required copies again after a jammed paper is expelled . since the copying operation is continuously restarted , the preset number of copies are precisely reproduced .
