A mechanism is provided for observing laser beam alignment with a start-of-scandetector chip 10, while the laser beam 12 is being scanned in a horizontal direction across a photo-conductor drum 14- The start-of-scandetector 10 is located on a target panel 16 along with the input ends of a plurality of fiber-optic bundles 18, 20, 22- 24, 26, 28 and 30. The input ends are in a vertical array with the input end 24 in the center of the array being horizontally aligned with the detector chip 10 whereby the scanned laser beam 12 will strike
