a method of aligning a laser printhead in an electrophotographic machine includes providing a fixture with a pair of fixed sensors . the fixed sensors are spaced apart along a length of a first fixture drum axis . each of the fixed sensors is fixed relative to a second of the fixed drums . the first fixture drum is provided with a pair of floating sensors . the floating sensors are spaced apart along the length of the first fixture drum axis . each of the floating sensors is fixed relative to the first fixture drum . a laser beam from the laser printhead is scanned across an outside surface of the first fixture drum , the fixed sensors and the floating sensors . an intersection of the scanned laser beam and the outside surface of the first drum defines a scan path . a first skew of the scan path relative to an axis of the first drum is measured using the floating sensors . a second skew of the scan path relative to an axis of the second drum is measured using the fixed sensors . the scan path of the laser beam is adjusted dependent upon each of the first skew and the second skew .
