ABSTRACT:
A carriage system for a printing apparatus is disclosed. The carriage system includes a movable carriage for carrying at least one ink pen, a carriage rod on which the carriage is rotatably mounted, an anti-rotation rail that is adjacent to one end of the carriage to prevent the rotation of the carriage in one direction, and a spring-loaded preloader coupled to an underside of the carriage to prevent the rotation of the carriage in the opposite direction and to urge the carriage against the anti-rotation rail. The preloader includes a preloader body made of a nonmetallic material, a roller operable to roll along a surface below the carriage, and a resilient spring.
