An automatic paper sensing apparatus for an ink jet printer which can supply and print sheets of paper can automatically subsequently sense the existence of paper when a message indicating the absence of paper is generated. A first arm is fixed to the actuator feed in the direction of a separator, a second arm is mounted rotatably around a hinge axis at one side of the separator moved by an adjustable lever so as to interlock slidably with the first arm, the second arm being supported elastically by a tension coil spring fixed at one side thereof to the separator, one side of the actuator feed can be attached and detached to and from an optical sensor by means of the interlocking of the first and second arms. When the actuator feed and the separator are provided with an arm which is slidably interlocked with each other, the automatic sensing apparatus can automatically sense the subsequent existence of paper in order to facilitate convenient use of the printer.
