(1)Pickup roller

This roller moves up and down to draw out a sheet of paper from the bypass tray or the drawer, and transport it to the feed roller.

(2)Feed roller

This roller transports the paper from the pickup roller to the registration roller.

(3)Separation roller

This roller is mounted against the feed roller. When two sheets of paper or more are transported from the pickup roller, the load of the torque limiter (spring) of the separation roller is greater than the frictional force between the sheets. As the result, the separation roller is stopped and the lower sheet of paper is not transported any further. When only one sheet of paper is transported from the pickup roller, the separation roller is forced to rotate following the feed roller.

(4)Transport roller

This roller transports the paper from the feed roller to the registration roller.

(5)Registration roller

Paper transported from the feed roller is pushed against the registration rollers, which aligns the leading edge of paper. The registration roller then rotates to transport the paper to the transfer section.

The following sensors detect the presence/absence of paper and the position of the paper being trans- ported, to control the ON/OFF of the corresponding rollers.

(6)Bypass paper sensor

This sensor detects whether paper is set in the bypass tray or not. If it is, bypass feeding is per- formed in preference to drawer feeding.

(7)Bypass feed sensor

This sensor detects whether paper has been transported from the bypass tray or not. It also de- tects whether the leading/trailing edge of paper has passed the feed sensor or not. This sensor is utilized to detect the jams such as paper misfeeding in the bypass unit.

(8)Drawer empty sensor

This is a transmissive-type sensor which detects the presence/absence of paper in the drawer using an actuator. When there is no paper in the drawer, the actuator blocks the light path of the sensor. Then the sensor determines that there is no paper.
