Start by pulling back the two latches near the top of the gun and open the cover until it’s locked open when you hear a clicking sound. Riff the first ten inches of labels and place the roll of labels between the roll holder tabs (grey). Now pull the pricing labels and drape them over the metal peel bar in eh front of the gun. Now close the cover until you hear another click shut. In the end, remove the labels from the backing paper to avoid any hurdles and start tagging products.
