디지털 복합기 용지이송기구의 가진원 분석

In this paper, we investigate the vibration source of sheet feeding apparatus installed in scanner cover of the digital MFP thorugh frequency analysis. Gearmesh frequency and motor generated frequency were calculated to analyse autospectrum. During driving state, we measure the vibration level. It was found from the siganl analysis that gearmesh frequency and motor generated frequency are identified as vibration source.
