The printing quality of the printer is influenced largely by the jitter. Although this jitter occurs by the various factor inside the apparatus, the biggest factor are the tooth profile error and backlash of the gear. The revolution variation of gear system is simulated by explicit dynamics finite element program and the jitter is calculated from revolution variation. The practicality to estimate the influence to the jitter by the tooth profile error and backlash for designing the gear system is confirmed.
