After a photoreceptor belt is ultrasonically welded, it is notched to remove weld splash that is created during the welding process. The notch chips sometimes adhere to the anvil by static. When the next photoreceptor belt is formed and welded, the notch chip left on the anvil is welded into the weld seam causing horn burn. Therefore, the photoreceptor belt is rejected as defective.
