A serial printer sometimes generates a vertical striped pattern in the printing image. This is known as jitter and caused by vibration of the print-head carriage system. The vibration of carriage is due to a lot of factors, step driving of the stepping motor, meshing between the belt and the pulley, meshing of the reduction gears, and friction of the carriage. In this paper, tow methods of passive vibration control for reducing the vibration the carriage are proposed. One is applying dynamic vibration absorbers, and another is adding a spring-damper element into the carriage system. The analysis is carried out by using a equivalent vibration system of linear motion. Calculation results show that the vibration characteristic of the carriage is improved.
