One of the causes of feeding problems in using paper-handling machines such as printers and copy machines is the curl of paper. In developing process of a new paper handling machines without many experiments the curl of paper cannot be prevented because the causes of the curl of paper have not been theoretically figure out yet. In this study, the curl of paper was observed using two experimental devices. One has a set of a heat roller and a steel roller, the other has a set of a heat plate and a back up plate. Based on the observations, the differences of the permanent strain and the degree of swelling of fiber on each side of paper were found newly as the causes of the curl of paper. Finally, mathematical models of the mechanisms of the curl of paper were proposed, and the availabilities of the models were verified by comparing the analytical results with the experimental ones.
