The tray unit and paper transport section is integrated in this LCIT.
Pick-up roller, feed roller, and separation roller used for this LCIT are the same as the bypass tray unit on the main machine.
The FRR feed method is used for feeding and separating, which the main machine also employs.
Idling
When the paper transport motor [G] starts, the paper transport roller [E] starts rotating.
The separation roller is stopped by the friction with the feed roller.
Paper Feed and Separation
When the paper feed motor [F] and the pick-up solenoid [A] are turned ON, the feed roller [D] starts rotating. Then the pick-up roller [B] also rotates and feeds the top sheet of paper on the feed tray.
The separation roller [C] contains a torque limiter. The friction between the separation roller and the feed roller [D] exceeds the limit of the torque limiter.
When two or more sheets of paper are fed, the torque limiter makes the separation roller [C] rotate to push the lower sheet of paper back to the tray.
When the paper feed sensor detects paper, the pick-up solenoid [A] turns OFF, and the pick-up roller [B] lifts away from the paper to reduce the resistance to paper feed.
The paper that is fed in is transported to the registration roller.
