A paper sensing apparatus of an office machine has a sensor actuator disposed to pivot with respect to a pivot center of a conveying roller by a printing paper when the printing paper is conveyed, and a sensing unit generating a paper sensing signal in accordance with a rotation of the sensor actuator. Accordingly, the paper sensing apparatus is capable of accurately sensing a leading end of the printing paper, and thus a top margin of the printing paper can be effectively controlled as the paper sensing apparatus is installed to be operated with respect to a rotation center of the conveying roller so that an error generated during sensing a paper top position due to a lengthened distance between the conveying roller and a transferring roller can be reduced.
A paper sensing apparatus for controlling a printing position of an image to be printed by sensing a leading end of a printing paper, for use in an office machine including a paper stacking unit containing sheets of printing paper, a pick-up unit picking up the printing paper stacked on the paper stacking unit, a conveying unit having at least one conveying roller to convey the paper picked up at the pick-up unit and one back-up roller, and an image forming unit to form an image on the printing paper conveyed by the conveying unit, comprising:
A paper sensing apparatus for controlling a printing position of an image to be printed on a printing paper by sensing a leading end of the printing paper passing along a path in an image forming apparatus, comprising:
36 The paper sensing apparatus of claim 10, wherein the roller unit comprises a shaft, and the sensor actuator comprises:
A paper sensing apparatus for controlling a printing position of an image to be printed on a printing paper by sensing a leading end of the printing paper passing along a path in an image forming apparatus, comprising:
A method of controlling a printing position of an image to be printed on a printing paper by sensing a leading end of the printing paper passing along a path in an image forming apparatus, comprising:
