Separation mechanism

• The separation roller is driven to rotate in the opposite direction from the paper transfer
direction. When transferring no or 1 sheet of paper, the separation roller rotates in the
paper transfer direction to transfer the paper to the paper transfer section because the
frictional force between the paper feed roller or the paper and the separation roller is
stronger than the frictional force of the torque limiter.
• When transferring 2 or more sheets of paper, the separation roller rotates in the reverse
direction to prevent the bottom sheet from being transferred because the frictional force
between the sheets is stronger than the frictional force of the torque limiter.
