PAPER FEEDING SYSTEM
8 - 6
8.3.3 Paper separation
This model is equipped with a separation roller which works to prevent multiple paper feeding. The
separation roller unit consists of the feed roller, separation roller, torque limiter, etc., as shown at right.
The feed roller is rotated by the feed clutch in the direction of the white arrow at the same timing as the
pickup roller rotation.
The figure at right shows how duplicate feeding is prevented: Since the friction between two sheets is
small, the lower sheet is not transported any further while the upper sheet is transported by the feed
roller in the direction of the black arrow.
Fig. 8-5
[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.
