In a serial printer, the printing is carried out line by line, while the print-head moves on papers or other print media. The positioning accuracy in moving time of the carriage, in which the print-head is mounted on, influences the picture quality of printing image directly. Usually, the carriage of serial printer uses a stepping-motor as driving source, and it is driven through meshing transmission elements : a couple of reduction gears and a couple of synchronous belt and pulley. Sometimes density non-uniformity is generated in the printing image, which is called jitter and is a main cause decreasing the picture quality of printing image. It has been found that the positioning error by the meshing vibration of synchronous belt is the most significant factor causing jitter.. In this paper, an theoretical analysis for the motion and vibration of the carriage system is provided, and the vibration displacement of the carriage due to the meshing vibration of synchronous belt, namely the dynamic transmission error, is discussed. The theoretical analysis is confirmed with calculations and experiments.
