[Example]
When only one sheet enters between the rollers:
Since the transporting force of the feed roller is greater than the braking force of the separation roller,
the separation roller follows the feed roller, making the sheet go forward to the registration roller.
When two sheets enter between the rollers at the same time:
Since the transporting force of the feed roller and the breaking force of the separation roller are greater
than the frictional force between two sheets, the paper A is transported to the direction of the black
arrow and the paper B is braked by the separation roller and is not transported any further.
