When loading ensure you position one of the open slots of the plastic core (on the roll) over the locking lug located on the backing plate of the dispenser. The tape should come off the roll at the 6 o'clock position unwinding in a clockwise direction.
Thread the leader of the tape through the rollers & back over the top of the roll. Wind the leader onto the paper windup roll located at the rear of the dispenser. Leader will roll up in an anticlockwise direction. Ensure paper liner is tensioned correctly (should not be loose).
