A rekeyable lock cylinder includes a lock cylinder body having an interior void and a plug assembly rotatably disposed in the lock cylinder body. The apparatus includes an image recording unit that performs a printing operation. In the preferred embodiment, the shuck arms are modified to incorporate springs such that when the engagement force is removed from the pipette tip box, the shuck arms are forced by the springs against the pipette tip box thereby displacing the pipette tip box from the pipette tips.
