ABSTRACT:
A carriage is driven along a carriage rod. The carriage includes a roller or a sled which runs along a track. As the carriage moves along the rod the roller or sled runs along the track. Defects in the roller or bumps along the track cause the carriage to rotationally vibrate about the carriage rod during movement. A vibration isolator (e.g., tuned spring) is included at the connection between the carriage and the roller or sled. Such isolator absorbs vibrations introduced by the roller, sled or track. The reduced vibrations lead to improved print quality for printers having smaller dot size or increased precision.
