Before installing label stock remove all extra tape and wrappers from the roll. Lower the Roll Guide and pull it outward to make room for your label stock. Place your roll of label stock on the Roll Arm and push it inward until it touches the Roll Stop. Flip up the Roll Guide and slide it inward until it touches the label stock. Insert the label stock into the feed area so that it is touching the fixed throat guide. Set the movable throat guide so that it is just touching the label stock. Continue to push the label until you feel resistance. Internal label sensors will detect it and turn on the automatic feed rollers to finish feeding the labels through the printer.
