A method of controlling an operation of an image sensor when the image sensor stops due to a mechanical error or a power interruption while moving along a scanning path in a certain direction to scan a document in an apparatus having a scanning function, and when the power is re-supplied, includes acquiring image information of an upper part of the image sensor by scanning the upper part of the stopped image sensor, determining a position of the image sensor based on the image information of the upper part of the image sensor, and controlling the image sensor to move to a home position by moving the image sensor to a right side by a certain distance and re-scanning a home sensing label when the image sensor is located in the home position and at a left side of the home position, or controlling the image sensor to move toward the home position when the image sensor is located in a right side of the home position.
