OPC 드럼용 튜브의 최적 설계에 관한 수치적 연구

Laser printer has been became one of essential machine for office automation due to its' moderate maintenance cost and fast printing speed. Photosensitive drum, also known as ope drum, is a very critical mechanical component of the laser printer. Quality of printed matter is influenced by few factors such as coating condition of organic photoconductive material, size of toner particle and structural strength of ope drum itself. In this paper, FEM analysis has been performed to consider strength of the drum and to decide proper geometric appearance of the drum.
