Abstract
A printhead gap adjustment mechanism for use in an imaging apparatus includes a worm gear coupled to a carrier shaft to transmit a rotational motion to the carrier shaft. A worm screw is positioned in rotational cooperation with the worm gear, the worm screw having an axis of rotation. A first cam is coupled to the carrier shaft. A first cam follower surface is disposed in proximity to the first cam. A guide device guides the carrier shaft in a translational direction substantially parallel to the axis of rotation of the worm screw. A rotation of the worm screw transmits rotational motion to drive the first cam via the worm gear and the carrier shaft, the first cam engaging the first cam follower surface to effect a translational motion of the worm gear in the translational direction, thereby effecting a movement of the printhead in the translational direction.
