B. Separation mechanism
• The separation roller [4] is driven in the opposite direction [2] to the paper feed direction [10] via the torque
limiter [1].
• The separation roller is pressed against the paper feed roller [8] by means of the spring [3] force [9] and the
pressure applied from the torque limiter.
• The friction force between the separation roller and the paper feed roller is limited by the torque limiter in
order to prevent multi-feed.
• When no paper exists between the separation roller and the paper feed roller or when the only one sheet of
paper is present, the separation roller is driven by the paper feed roller in the direction of arrow [5] since the
torque is over the limit.
• When multiple sheets of paper are fed, the separation roller reverses the direction of rotation [2] (opposite to
the paper feed roller)
• the separation roller the direction of rotation [2] (opposite to the paper feed roller) feeds the lower paper [7]
that contacts with the separation roller back to the tray [6]. The drop in frictional force between the two roll-
ers due to the multiple sheets causes the counter rotating of the separation roller.
