In this investigation, the slip-phenomenon that occurs in the paper feeding system and deteriorates the accuracy of printing is studied. The system presented in this paper is such that the printing paper is pinched with two rollers. The driving roller has protrusions on their surface and the driven roller is coated with rubber. The slip value that is calculated by the velocities of the driving roller and the paper is used to represent the amount of slip-phenomenon in this paper. In the experimental study, characteristics and contribution ratios of various factors with respect to the slip value are found. In theoretical study, mathematical model of the paper feeding system based on elastic theory is developed to calculate the slip value. Consequentially, the slip value is calculated with these results. The analytical results show good agreement with the experimental ones.
