This paper discusses lateral paper motion characteristics of a paper transfer mechanism. In this paper, the lateral paper motion characteristics of a paper transfer mechanism is investigated experimentally with an experimental setup consists of a long rubber-layerd roller and a steel roller. Rubber thickness, steel-roller skew angle and load weight are changed in experiments. The experimental result showed that the skew of steel roller doesn't cause in-plane rotation of the paper but lateral paper motion, and the paper is almost fed in the feeding direction of the steel roller.
