ABSTRACT:
A method of cutting off recording paper on a facsimile apparatus is disclosed in which the recording paper wound as a roll is sequentially fed through the apparatus so that the paper is cut off by a cutter after the recording on each sheet area of the paper is performed. The method comprises a stop in which the torque of an electric motor is transmitted to a platen roller through a gear train so that the recording on the (n+1) th-sheet area of the recording paper is performed continuously after the recording on the nth-sheet area of the paper; a step in which when the boundary between the nth-sheet area and the (n+1)th-sheet area has reached the cutoff position, the recording on the (n+1)th-sheet area is temporarily stopped and the backlash of the gear train is compensated for by rotating the motor backward; a step in which the recording paper is cut off by the cutter; and a step in which the backlash of the gear train is compensated for again by rotating the motor forward. As a result, although the recording paper is cut off by the cutter while recording on the (n+1)th-sheet area, the recorded image on the (n+1)th-sheet area does not have blank spaces or overlapped recording. In addition, the time of communication to the facsimile apparatus through a telephone line is shortened to reduce the cost of the communication.
